Fullness in Christ

A Christian is not saved because he does things for God; rather, he is one for whom God has done great things to bring about salvation. Eternal salvation is never about what we accomplish for Him, but about what He has accomplished for us through the person and work of the Lord Jesus Christ on the cross (Eph 2:8-9; Tit 3:5). Jesus is the eternal Son of God (John 1:1, 14), and “in Him all the fullness of Deity dwells in bodily form” (Col 2:9). In His humanity, Jesus lived a sinless life (1 John 3:5), and willingly went to the cross and died a death He did not deserve (Mark 10:45; John 10:18), and provides the life we can never earn (John 3:16; 10:28; 1 Pet 3:18). At Calvary, Christ bore our sins in His body (1 Pet 2:24), paid the full penalty we deserved (Rom 5:8), and secured the gift of eternal life for all who believe in Him (John 3:16). Once eternal life is received, it is locked in (John 10:28), we are sealed forever (Eph 1:13-14), and it cannot be revoked (Rom 11:29).

Once saved, the humble and obedient believer is called to walk in step with God, glorifying Him and edifying others (1 Cor 10:31; 1 Th 5:11). This new walk is not fueled by personal willpower but by divine enablement (Eph 5:18). God Himself has equipped the believer for such a life by placing him into union with Christ (1 Cor 1:30), granting him new life (2 Cor 5:17), indwelling him with the Holy Spirit (Rom 8:9), entrusting him with a spiritual gift (1 Pet 4:10), and providing time and opportunity for growth (2 Pet 3:18). God, in His grace, has supplied all that is necessary for life and godliness, for “His divine power has granted to us everything pertaining to life and godliness” (2 Pet 1:3). There’s no excuse for failure in the Christian life. None whatsoever.

As the believer advances toward spiritual maturity (Heb 6:1), his growth is marked by walking by faith (2 Cor 5:7) and applying the spiritual resources God has given. The Spirit empowers obedience (Eph 5:18), the Word renews the mind (Rom 12:2), and prayer cultivates dependence (Phil 4:6-7). These are the means of grace through which the believer experiences the fullness of life Christ promised. Jesus said, “I came that they may have life, and have it abundantly” (John 10:10). He came to give, not to get. While eternal life is a free gift received at the moment of faith in Christ (phase one), the abundance He promises is enjoyed in the believer’s daily walk (phase two). As born-again Christians, we step into this fullness when we humbly submit to Him (Jam 4:7), learn and live His Word by faith (2 Tim 3:16-17), and live sacrificially for the good of others (Phil 2:3-4). These blessings belong to phase two of the Christian life—blessings contingent upon obedience and faith—and they overflow in the joy of fellowship with Christ (John 15:10-11). Abundant life is not automatic; it is cultivated in the soil of obedience and watered by daily communion with the Savior. The Christian who is disobedient to God and pursues sinful living brings down God’s discipline (Heb 12:6), and forfeits blessings now and in eternity (1 Cor 3:12-15).

The maturing Christian learns to keep his focus on Christ, drawing strength from Him in every circumstance (Phil 4:13). He understands that the Christian life is not a sprint of self-effort but a steady walk of faith, empowered by God’s Spirit and informed by God’s Word (Gal 5:16, 25). As he lives in fellowship with God, his life begins to bear the fruit of the Spirit—love, joy, peace, and other virtues that reflect Christ’s character (Gal 5:22-23). These virtues do not develop overnight but are the steady harvest of a heart yielded to God over time (Col 1:10).

This is the ideal Christian life—a life of humility and obedience that glorifies God and edifies others. It is not lived in order to keep salvation, nor to prove oneself worthy of it, but as a grateful response to the unearned grace that saved us in the first place (Col 3:17). It is the life God designed for His children—a life lived by faith, under grace, and in the power of the Spirit, so that in all things He might receive the glory and honor due His name (Rom 11:36). And when such a life is lived, it becomes a visible testimony to the watching world that Jesus truly changes everything. Jesus said, “Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven” (Matt 5:16).
