It is possible for a Christian to sin, and to sin as badly as any unbeliever. However, unlike the unbeliever, God disciplines His own (Heb 12:5-11), and, if necessary, disciplines to the point of death (1 Cor 11:30; 1 John 5:16). This need not be the case. The Christian is called to a life of holiness (1 Pet 1:15-16), and this means learning to walk with God and do His will. Though we still possess a sin nature, Christians know victory because of our union with Christ (Rom 6:6, 11-13), and our walk of faith (Heb 10:38; 11:6). When filled with the Spirit (Eph 5:18), and walking by means of the Spirit (Gal 5:16), we can learn to embrace trials and even rejoice in them (Rom 5:3-5; Jam 1:2-4).
