A perversion means diverting from the true intent or purpose of something. God created sex to be solely between a married couple (one naturally born man married to one naturally-born woman). But since the Fall sexuality has gone through numerous mutations of evil. Sexual perversions of many types are directly mentioned in the Bible (Gen. 19:1-38; Exod. 20:14; 22:19; Lev. 18:22, 23; 20:13; Deut. 23:17; 27:21; Matt. 5:28; Rom. 1:26-27; 1 Cor. 6:9; 1 Tim. 1:10; Heb. 13:4; Jude 1:7; Rev. 21:8, et. al.). And anything that is not directly mentioned is implied by such verses like Ephesians 5:3 which says, “Don’t let sexual sin, perversion of any kind, or greed even be mentioned among you. This is not appropriate behavior for God’s holy people (GWT).
