The Christian faith begins the moment a person believes in Jesus Christ as Savior, trusting Him alone for the free gift of eternal life (John 3:16; Acts 16:31; Eph 2:8-9). At that instant, God forgives sins, declares the believer righteous (Rom 3:28; 5:1), and grants eternal security (John 10:28). This starting point is not achieved by works, reform, or religious ritual, but by faith alone in Christ alone. The Christian life then continues by walking with God daily through faith, learning and applying His Word, and living in dependence on the Holy Spirit (2 Cor 5:7; Gal 5:16; 2 Tim 3:16-17). Growth in grace is a lifelong process as the believer renews the mind (Rom 12:2), pursues godliness (Tit 2:11-12), and serves others in love (Gal 5:13). Failures and setbacks do not undo salvation, but God disciplines and restores His children, calling them back to fellowship with Him (1 John 1:9; Heb 12:6). Thus, the Christian faith begins with a decisive act of faith in Christ for salvation and continues with a lifelong walk of faith, obedience, and spiritual growth until the believer is perfected in the presence of the Lord (Phil 1:6; 1 John 3:2).
