There are at least eight vice lists in the New Testament (Mark 7:21–22; Rom. 1:24–31; 13:13; 1 Cor. 6:9–10; Gal. 5:19–21; Col. 3:5–9; 1 Tim. 1:9–10; Rev. 21:8), and sexual immorality is included in every one of these. In fact, in seven of the eight lists there are multiple references to sexual immorality (e.g., impurity, sensuality, orgies, men who practice homosexuality), and in most of the passages some kind of sexual immorality heads the lists. You would be hard-pressed to find a sin more frequently, more uniformly, and more seriously condemned in the New Testament than sexual sin.
