A Brief Summary of Biblical Sexuality
Homosexuality is another perversion of sex expressly forbidden in Scripture (Lev 18:22; 20:13). It is contrary to sound doctrine and not in accordance with the gospel (1 Tim 1:10–11). Homosexual sex between men or women stems from dishonorable, sinful passions and is a shameless act that abandons natural sexual relations between a husband and a wife (Rom 1:26–27; e.g., Gen 19:5, 7; cf. 2 Pet 2:7; Jude 7). God punishes this sin by giving the sinner over to the sin itself and its various consequences (Rom 1:27).
God created man as male and female (Gen 1:27) with the capacity for sexuality, properly taking place only between a husband and a wife (Gen 2:24; Heb 13:4) for the purposes of procreation (Gen 1:28; 9:1) and relational enjoyment (Gen 2:18, 24). In a fallen world, sex in marriage helps to restrain temptation to sexual sin (1 Cor 7:2, 5).
As Christians, we must remember that our bodies belong to the Lord, are members of Christ, and are temples of the Holy Spirit, having been bought with the blood of Christ (1 Cor 6:13, 15, 19–20; 1 Thess 4:7–8; cf. 1 Pet 1:18–19). It is God’s will for us to control our bodies in holiness and honor (1 Thess 4:3–4). When Christ returns, our bodies will be changed to be like the Lord Jesus Christ’s body, perfect and incapable of sin (1 Cor 15:51–58; Phil 3:21; 1 John 3:2).
Unbelievers reject God’s truth, however, and live according to the impure lusts of their hearts, leading to dishonorable actions with their bodies, to one degree or another (Rom 1:18–20, 24; 1 Thess 4:5).
Lust itself is sin, that is, the willful longing for sex outside of marriage. This lust can take place by looking at someone with lustful intent (Matt 5:28; cf. Jas 1:14–15).
