The spiritual life is inseparably connected to the walk of faith, for to “walk by the Spirit” (Gal 5:16) is to “walk by faith” (2 Cor 5:7). The former assumes the latter. God the Holy Spirit inspired the Scriptures (2 Tim 3:16-17; 2 Pet 1:20-21), ensuring the written text is God’s authoritative revelation, the very “Word of God, which performs its work in you who believe” (1 Th 2:13b). It follows that God the Holy Spirit will instruct us in the Word He authored.[1] Jesus told His disciples, “the Holy Spirit…will teach you all things, and bring to your remembrance all that I said to you” (John 14:26), and “He will guide you into all the truth” (John 16:13). Paul said the Word of God is “the sword of the Spirit” (Eph 6:17), indicating that the Spirit works through Scripture to equip us for spiritual battles and faithful living. The “Word of God is living and active” (Heb 4:12) because the Spirit of God is living and active. The Spirit of God leads us by means of the Word of God, enabling us to understand, recall, and apply it to our lives by faith.
Furthermore, the fruit of being “filled with the Spirit” (Eph 5:18) is similar to the fruit of a mind saturated with God’s Word, where “the word of Christ richly dwells within” us (Col 3:16a). Being filled with the Spirit leads to “speaking to one another in psalms and hymns and spiritual songs, singing and making melody with your heart to the Lord; always giving thanks for all things in the name of our Lord Jesus Christ to God, even the Father” (Eph 5:19-20). Similarly, letting the Word of Christ richly dwell within us results in “psalms and hymns and spiritual songs, singing with thankfulness in your hearts to God” (Col 3:16b). The fruit of being filled with the Spirit and a mind saturated with God’s Word is similar, because the Spirit works though His Word. Wiersbe states, “In his Letter to the Ephesians, Paul emphasized being filled with the Spirit; in his Letter to the Colossians, he emphasized being filled with the Word. But the evidences of this spiritual fullness are the same!”[2] Radmacher states:
“In Ephesians 5:18 Paul wrote, “Be filled with the Spirit,” and in Colossians 3:16 he said, “Let the word of Christ dwell in you richly.” Though these commands differ, the results are the same, thus suggesting their close relationship. These verses therefore suggest that it is not possible for God’s Word to dwell in believers unless they are filled with the Spirit; and conversely, Christians can’t be filled with the Spirit without the Word of Christ dwelling in them.”[3]
To walk by faith is important to the spiritual life. Faith is a mental activity that relies on information. Biblically, faith is never blind. It is never an irrational leap into the unknown. Rather, it is a reasonable response that follows reliable information. Faith trusts facts. For example, none of us have personally seen the resurrected Christ, yet the record of Scripture is historically true and reliable, based on eyewitness accounts of people who walked with Jesus (Luke 1:1-4; John 20:27, 30-31; 21:24; Acts 4:20; 10:39; 1 Cor 15:3-8; 1 Pet 5:1; 2 Pet 1:16-19; 1 John 1:1). After Jesus’ resurrection, He appeared to many people and gave proof of victory over sin and death. These eyewitnesses include Mary Magdalene and other women (John 20:10-18; Matt 28:8-9), two disciples on the road to Emmaus (Luke 24:13-32), the disciples without Thomas (John 20:19-25), the disciples with Thomas (John 20:26-29), the disciples by the Sea of Galilee (John 21:1-23), Peter, James, and more than 500 brethren at one time (1 Cor 15:5-7), the disciples at Jerusalem before His ascension (Acts 1:3-9), Stephen at the time of his martyrdom (Acts 7:56), Saul on the road to Damascus (Acts 9:1-6; 1 Cor 15:8), and John on the island of Patmos (Rev 1:9-18).
Faith in Christ comes from accurate historical accounts, so that even though we do not see Jesus, we believe in Him. Jesus told Thomas, “Blessed are they who did not see, and yet believed” (John 20:29b). The writer of Hebrews said, “faith is confidence in what we hope for and assurance about what we do not see” (Heb 11:1). Peter communicated something similar to believers, saying, “though you have not seen Him, you love Him, and though you do not see Him now, but believe in Him, you greatly rejoice with joy inexpressible and full of glory, obtaining as the outcome of your faith the salvation of your souls” (1 Pet 1:8-9). These early Christians rejoiced even though they had not seen Jesus personally. They accepted the testimony of reliable witnesses who had known Jesus, and their faith in Him resulted in the salvation of their souls.[4]
Believing in Jesus as our Savior comes after we hear and accept as true the good news that Christ died for our sins, was buried, and rose on the third day (1 Cor 15:3-4), thus conquering sin and death. Jesus accomplished what we cannot—our eternal salvation. When we hear this good news of what Jesus has done for us, we can place our faith in Him (John 3:16; Acts 4:12) and be fully assured of forgiveness of sins (Acts 10:43; Eph 1:7) and eternal life (John 10:28; Rom 6:23). The benefits of the cross are applied to us the moment we believe in Jesus as our Savior. This simple act of faith results in our justification before God, “For we maintain that a man is justified by faith apart from works of the Law” (Rom 3:28), and “we have believed in Christ Jesus so that we may be justified by faith in Christ and not by the works of the Law” (Gal 2:16). Eternal salvation is by grace alone (Eph 2:8-9), through faith alone (Rom 3:24, 28; 5:1), in Christ alone (Acts 4:12).
Live by Faith
After being born again by faith alone in Christ alone, we are to continue in faith. Paul wrote, “as you have received Christ Jesus the Lord, so walk in Him” (Col 2:6). We received Jesus by faith, and after being born again, we are to “walk by faith, not by sight” (2 Cor 5:7). The word “walk” translates the Greek verb peripateō (περιπατέω), which is here used as a metaphor for how we live, behave, or habitually conduct our lives. To walk by faith means we learn and apply God’s Word to our lives (i.e., marriage, family, education, work, finances, etc.). It means obeying God’s directives, claiming His promises, and utilizing His resources for our daily problems. We are also instructed to “walk by the Spirit” and not the flesh (Gal 5:16). When we live by faith and depend on the Spirit for strength and guidance, we “walk in a manner worthy of the calling” with which we have been called (Eph 4:1).
As Christians, we are instructed to learn God’s Word that we might come to know our new identity in Christ and lay hold of the many blessings God has provided for us as His children. Gospel information started our journey of faith, and Bible doctrine is the basis for our spiritual walk and advance to maturity. The advancing believer is living the righteous life that God expects, for He says, “My righteous one shall live by faith” (Heb 10:38), and “faith is being sure of what we hope for, being convinced of what we do not see” (Heb 11:1 NET). To live by faith in God and His Word pleases Him, for “without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him” (Heb 11:6). Paul said, “we have as our ambition…to be pleasing to Him” (2 Cor 5:9).
Christians who fail to live by faith, who choose not to learn and/or live by God’s Word, will default to humanistic philosophies, values, and experiences. In immature or carnal Christians, experiences and feelings will be regarded as more real, reliable, and important than God and His Word. Though we can enjoy our experiences and feelings (when they align with God), these are not stable, so we must be careful not to prioritize them or make them the base of operations. Divine wisdom should be our base of operations, as God wants us to learn and live His Word, to trust Him in all things, and to live by faith as obedient-to-the-Word children. When feelings rise high, faith must rise higher, lest we get bogged down and trapped in faulty reasonings that enslave and hinder our spiritual life and victory. The walk of faith requires discipline of mind and will.
Ultimately, “whatever is not from faith is sin” (Rom 14:23). Faith starts with God and His directives and promises. Once we learn about God’s directives, provisions and promises, He expects us to live by them, to be “doers of the word, and not merely hearers who delude” ourselves (Jam 1:22). It is possible to learn God’s Word and not apply it by faith, which is why James wrote, “to one who knows the right thing to do and does not do it, to him it is sin” (Jam 4:17). It is a sin not to live by faith. The writer to the Hebrews warned his readers, saying, “Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God” (Heb 3:12). After hearing God’s Word, it is evil for a Christian not to believe it. It’s evil because God’s Word is absolute truth (2 Sam 7:28; Psa 119:160; John 17:17), and rejecting or doubting it implies that God, who cannot lie (Num 23:19; Tit 1:2; Heb 6:18), is untrustworthy, which is an affront to His perfect nature. This evil behavior was exemplified by the Israelites in the wilderness, for after they’d been delivered from Egyptian bondage, they failed to live by faith (Num 14:11), angered the Lord (Psa 95:8-11), and so forfeited the blessing of inheriting the land (Heb 3:15-18). The danger for us as Christians is that we might know God’s directives and promises, but fail to apply them by faith, and never benefit from His blessings. The writer to the Hebrews said, “Therefore, let us fear if, while a promise remains of entering His rest, any one of you may seem to have come short of it. For indeed we have had good news preached to us, just as they also; but the word they heard did not profit them, because it was not united by faith in those who heard” (Heb 4:1-2).
Hindrances to the Walk of Faith
The hindrances of Christian faith are ignorance of God’s Word (Hos 4:6), irrational and unwarranted fears (2 Tim 1:7), failure to claim promises (Heb 3:12), unwarranted self-reliance (Prov 3:5-6; Jer 17:5-7), yielding to the pressures and pleasures of the world (Jam 4:4; 1 John 2:15-16), and choosing the desires of the flesh rather than God’s will (Gal 5:16-17; 1 Pet 2:11). Ignorance of God’s Word guarantees failure in the Christian life, for we cannot live what we do not know. This is why we are to study God’s Word (2 Tim 2:15; 3:16-17; 1 Pet 2:2; 2 Pet 3:18), renovate our minds (Rom 12:1-2), live by faith in God (Prov 3:5-6; 2 Cor 5:7; Heb 10:38; 11:6), and walk by the Spirit rather than the desires of the flesh (Gal 5:16).
God’s Word is Reliable
Though Peter had personally seen and heard Christ (2 Pet 1:16-18), he told his readers, “We have the prophetic word made more sure” (2 Pet 1:19a). Other translations read, “we possess the prophetic word as an altogether reliable thing” (2 Pet 1:19a NET), and “We also have the prophetic message as something completely reliable” (2 Pet 1:19a NIV). The words “more sure” translate the Greek adjective bebaios (βέβαιος) which means reliable, dependable, or trustworthy. According to BDAG, it refers to “something that can be relied on not to cause disappointment.”[5] Kenneth Wuest states, “The idea here is of something that is firm, stable, something that can be relied upon or trusted in. The idea in the Greek text is, ‘We have the prophetic word as a surer foundation’ than even the signs and wonders which we have seen.”[6] Robert B. Thieme Jr., notes, “God’s Word is more real than empirical knowledge, more reliable than anything seen, heard, or felt (2 Pet 1:12–21). Unlike the grass that withers and the flowers that fade, ‘the word of our God stands forever’ (Isa 40:8). God guarantees that His Word never goes forth without accomplishing His will (Isa 55:11).”[7] The point is that God’s Word is absolutely reliable, “to which you do well to pay attention as to a lamp shining in a dark place” (2 Pet 1:19b).
In summary, the Christian life is a walk of faith that is empowered by the Holy Spirit and grounded in God’s Word. Faith is not blind or speculative; rather, it is a confident trust in the revealed truths of Scripture, producing a life that seeks to honor God through obedience and reliance on His promises. To walk by faith is to live in active dependence on God, letting His Word shape our thinking, guide our actions, and strengthen us for every challenge we may face. The Holy Spirit works through the Scriptures to instruct, remind, and empower us, enabling us to live the Christian life. As believers, we are called to a disciplined life of learning and applying God’s Word, and not trusting in experiences or feelings. The walk of faith is pleasing to God, honors Him, edifies others, and brings us mental and emotional stability.

[1] Divine revelation came by means of God the Holy Spirit. On three occasions Luke makes this very claim, saying, “Brethren, the Scripture had to be fulfilled, which the Holy Spirit foretold by the mouth of David concerning Judas, who became a guide to those who arrested Jesus” (Acts 1:16; cf. Psa 109:8), and “the Holy Spirit, through the mouth of our father David Your servant, said, ‘Why did the Gentiles rage, and the people devise futile things’” (Acts 4:24-25; cf. Psa 2:1), and “The Holy Spirit rightly spoke through Isaiah the prophet to your fathers” (Acts 28:25; cf. Isa 6:9). In each of these examples, the prophets were the mouthpiece of God, reveling His thoughts and expectations to people. Furthermore, the Spirit illuminates His Word to those with positive volition (John 7:17; 1 Cor 2:15). Unbelievers with negative volition suppress God’s revelation (Rom 1:18-20), and reject the things of the Spirit, which they “cannot understand” and regard as foolishness (1 Cor 2:14). Paul wrote, “Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God, which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words” (1 Cor 2:12-13).

[4] The apostle John was an eyewitness to the life, death, burial, and resurrection of Jesus, and like other eyewitnesses (Matthew, Mark, and Luke), he documented the historical events of Messiah. The whole of John’s Gospel had a purpose, and that was to convince people that Jesus is the Messiah and that if they believed in Him, they would have eternal life. John wrote, “many other signs Jesus also performed in the presence of the disciples, which are not written in this book; but these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name” (John 20:30-31). What John recorded in his Gospel is historically accurate and sufficient to lead a person to believe in Jesus as the Messiah and, after believing in Him, to be blessed with eternal life. That’s good news! When we preach Christ, we provide the necessary information for others to make an intelligent decision to believe in Him for eternal life. The gospel is good news information about the death, burial, and resurrection of Jesus (1 Cor 15:3-4). At a moment in time, a single act of believing in Jesus as our Savior will save us eternally. The Jesus we believe in is the God-Man (John 1:1, 14; Col 2:9), the Jewish Messiah (Matt 1:1, 17), who was sinless (1 John 3:5), died a substitutionary death for everyone (Mark 10:45; Rom 5:8), paid our sin-debt in full (Col 2:14; Heb 10:10, 14), was resurrected on the third day (Acts 10:40; Rom 6:9), and is the only Savior of mankind (John 14:6; Acts 4:12). The only response from us is to accept the good news and believe in Jesus as our Savior, for “whoever believes in Him shall not perish, but have eternal life” (John 3:16).
