1. Because the main purpose of the event is to do something God condemns—committing lasciviousness (indecent dress, touching, and/or body movements that stir up lust) (Gen. 39:12; Matt. 4:3-4; 5:28; Rom. 13:11-13; Gal. 5:19-21; Col. 3:17; 1 Thess. 5:21-22; 1 Tim. 2:9-10; 1 Pet. 2:11; 4:3-4).
2. Because we don’t want to support/embolden/encourage those who are sinning by our attendance (1 Cor. 10:23-33; Eph. 5:11-12; 1 Tim. 5:22; 1 Pet. 4:4; cf. 2 Cor. 6:14-18; 2 John 11).
3. Because we don’t want to give anyone, whether Christians or non-Christians, the impression that we condone sin (1 Cor. 8:9-13; 10:23-33; Eph. 5:11; Rom. 14:7,13,16; 1 Pet. 2:12).
4. Because we don’t want to be tempted to sin, and we don’t want to tempt others to sin (Josh. 7:21; 2 Sam. 11:2-4; Matt. 4:3-4; 14:6; 18:6-7; Rom. 13:14; Php. 4:8; 1 Thess. 3:5; 5:22; 2 Tim. 2:22; 1 Pet. 2:11; Jam. 1:13).
5. Because God wants us to protect our reputations, which will also cause Him to be glorified (Prov. 22:1; Eccl. 7:1; Matt. 5:16; 1 Cor. 6:18-20; 10:31; 1 Tim. 4:12; 1 Pet. 2:12).
6. Because we must be holy—different from the world (Exo. 23:2; John 17:17; Rom. 6:1-23; 12:1-2; 2 Cor. 5:17; Titus 2:11-14; 1 Pet. 1:15-16; Jam. 1:27; 4:4,7; 1 John 2:15-17).
7. Because we would rather seem strange to the world than be strangers to God (Matt. 7:21-23; John 15:18-19; Acts 17:20; Eph. 2:12; Titus 2:14; Jam. 4:4; 1 Pet. 2:9-12; 4:4; 1 John 2:3, 4).
8. Because we absolutely hate evil, knowing that sin is what caused our Savior to die the most excruciating death (Psalm 119:104, 128; Isa. 52:14; 53:3-11; Matt. 26:28; 27:24-54; Rom. 1:32; 5:8; 12:9; 1 Cor. 16:13; 2 Cor. 5:21).
9. Because we are in love with righteousness, knowing that our God is the embodiment of righteousness (Psalm 116:5; Rom. 12:9; 1 Cor. 13:6; Heb. 1:9).
10. Because we love God more than anything/anyone, and our greatest desire is to be in Heaven with Him (Eccl. 11:9; Matt. 6:33; 22:36-40; 25:34; John 12:48; 14:1-6; 1 Cor. 6:9-11; Gal. 5:19-21; Php. 1:21; Col. 1:5; 3:1-3; Heb. 11:13-16; 1 Pet. 1:3, 4; 2 Pet. 3:10-13).
