Living by faith is the Christian way. God expects us to trust Him at His word, which is plainly understood, believed, and applied. Studying the Bible and applying it to life are comparable to breathing in and breathing out, as both are necessary for living. Much of our mental and social stability depends on how well we know the Word of God and apply it to life. The Lord states, “My righteous one shall live by faith; and if he shrinks back, my soul has no pleasure in him” (Heb 10:38). And we know that “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). Scripture reveals that only God and His Word are absolutely true (Psa 119:160; John 17:17), and never fail (Matt 24:35; Tit 1:2; Heb 6:18). In contrast, we learn that people fail (Jer 17:5; cf. Pro 28:26), money fails (Psa 62:10), the government fails (Psa 146:3), and the creation fails (Matt 24:35). As we look at the Greek New Testament, we see how the word faith is used three ways:
- Faith, as a verb (πιστεύω pisteuo), means “to consider something to be true and therefore worthy of one’s trust.” It means to believe, trust, or have confidence in God (Heb 11:6; cf. Rom 4:3), Jesus (Acts 16:31; 1 Pet 1:8), and Scripture (John 2:22). Unreliable people should not be trusted (Matt 24:23, 26; John 2:24).
- Faith, as a noun (πίστις pistis), often refers to “that which evokes trust and faith…the state of being someone in whom confidence can be placed, faithfulness, reliability, fidelity.” The word is used with reference to God who is trustworthy (Rom 3:3; 4:19-21), and of people who possess faith (Matt 9:2, 22; 21:21), which can be great (Matt 15:28; cf. Acts 6:5; 11:23-24), small (Matt 17:19-20), or absent (Mark 4:39-40; cf. Luke 8:25). It is also used of Scripture itself as a body of reliable teaching (i.e. Acts 14:22; 16:5; Rom 14:22; Gal 1:23; 2 Tim 4:7).
- Faith, as an adjective (πιστός pistos), describes someone “pertaining to being worthy of belief or trust, trustworthy, faithful, dependable, inspiring trust/faith.” The word is used both of man (Matt 25:23; 1 Cor 4:17; Col 1:7; 1 Tim 1:12; 2 Tim 2:2; Heb 3:5), and God (1 Cor 1:9; 10:13; 2 Tim 2:13; Heb 10:23; Rev 1:5).
Biblical facts about faith:
- Faith demands an object (Acts 16:30-31).
- Faith is exercised with a view to receiving a benefit (John 3:16).
- The object of faith gets the credit (Rom 4:19-21).
- Salvation comes by faith in Jesus (Acts 4:12; 1 Cor 15:3-4; Gal 3:26; Eph 2:8-9).
- Faith is the only thing that pleases God (Heb 11:6).
- God expects us to live by faith (Rom 1:17; Heb 10:38).
- Faith is part of the fruit of the Holy Spirit (Gal 5:22-23).
- By faith we apply the word of God (Matt 7:24-25; John 13:17; Jam 1:22).
- By faith we claim promises (Heb 6:11-12; 2 Pet 1:4).
- It is possible to have God’s promises and not benefit from them (Heb 4:2).
- Our faith will be tested (1 Pet 1:6-7).
- Our faith overcomes fear (Deut 31:6-8; Isa 41:10-13).
- Trusting God produces mental stability (Isa 26:3; Phil 4:6-11).
- Faith can be strengthened by others (Acts 14:21-22; 16:5; Rom 1:12)
Faith in God results in a change of attitude and actions about everything. By faith, “we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible” (Heb 11:3). By faith we have confidence that God controls the circumstances of our lives, that He “causes all things to work together for good to those who love God, to those who are called according to His purpose” (Rom 8:28). Even the trials we face help to produce humility (Dan 4:37; Matt 23:12), and develop the character of God in us (Rom 5:1-5). James wrote, “Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance. And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing” (Jam 1:2-4). Such a faith response makes us better rather than bitter. By faith we obey God’s commands to love and serve (Gal 5:13), be tolerant (Eph 4:2), kind, tenderhearted and forgiving (Eph 4:32), and to regard others as more important than ourselves (Phil 2:3-4).
Satan, and his world-system, will strive to get the believer to rely upon anything and everything other than God and His Word. If the believer falls into this trap, he will experience worry, frustration, anxiety, and eventually a deep-rooted sense of despair. God wants us to have mental stability (Isa 26:3), love (1 John 4:16-17), contentment (Phil 4:11-13), and every other attitude that brings an abundant life (John 10:10). Only through a life of faith can we know the blessings that belong to every Christian.

 Though I’m looking at the Greek, it should be noted that the Hebrew אָמַן aman carries the same basic meaning as πιστεύω pisteuo. In fact, the LXX translates Genesis 15:6—a passage quoted by NT writers (Rom 4:3; Gal 3:6; Jam 2:23)—by using the Greek verb πιστεύω pisteuo.
