Those practises that the Bible condemns as sinful must not be practised by Christians, such as lying or deceit of any kind (Ex. 20:16; Matt. 5:37; Eph. 4:25), coarse language (Ex. 20:7; Eph.5:4), pornography (Phil.4:8; Eph.5:3-4; 1 Jn.3:3), theft or fraud (Ex.20:15; Eph.4:28), physical and verbal aggression or sexual harassment (Ex.20:13; Gal. 5:24; 1 Tim.3:3; 2 Tim.2:24), substance abuse including the abuse of tobacco, alcohol, and drugs (1 Cor. 6:19-20), criminal activities (Rom.13:1-7; 1 Pet.2:13-15), covetousness (Ex. 20:17; Heb.13:5), divisiveness among God’s people (1 Cor.1:10-13; Eph.4:3; Phil.2:3-4; 1 Tim.5:19; Tit.1:6; 3:10), and the like.
Rather, the Bible affirms that Christians must demonstrate the fruit of the Spirit in their attitudes and actions (Gal. 5:22-23), walk worthy of their calling (Eph. 4:1-2), dwell together in a loving, respectful unity (Phil. 3:2-4), maintain a vibrant and effective testimony for God in the world (Matt. 5:13-16), pursue holiness in all aspects of their lives (2 Cor. 6:14, 17; 1 Pet. 1:16), and, generally, to walk as Jesus walked (1 John 2:6).
