What does the Bible teach about homosexuality?
Just because a person may be heterosexual does not mean that they are necessarily moral: they might still be engaging in child molestation, adultery, rape, etc.
However, it is possible to be in God’s will and be engaging in heterosexual behavior, within the guidelines that God has given; it is not possible to be engaging in homosexual behavior and be in God’s will.
According to humanistic philosophy, which has greatly influenced politics and morality in Western culture, values are autonomous (each person deciding what is right in their own eyes) and relative. However, this is an unlivable philosophy, for many reasons. On the other hand, the biblical view of human sexuality can be found in passages such as Matthew 19:3-9– male and female, joined together in marriage, with exclusive sexual access to one another.
One man and one woman for one life time is God’s perfect will regarding human sexuality.
While God does permit divorce and remarriage in certain situations, homosexuality is allowed under no circumstances. Acts 15:20 and 1 Corinthians 6:18 remind us that any sexual activity out of the marital bond between one man and one woman is forbidden by God.
Adultery, pre-marital sex, polygamy, and bestiality are all forbidden by the clear biblical guidelines of sexuality. Leviticus 18:6-18 forbids incest, 18:23 forbids bestiality, 18:22 clearly forbids homosexuality. There are certain sins, according to this passage, that destroy a nation and homosexuality is one of them.
We should not force Old Testament law on unbelievers; however, homosexuality will destroy a nation and therefore we ought to work and pray to prevent its foothold in our culture. Romans 1:26,27 shows that homosexuality is one of the consequences of rejecting God and how destructive it is.
But perhaps the most important lesson comes from 1 Corinthians 6:9-11 which lists numerous sins (not just homosexuality) that are characteristic of the unsaved, but also says that all of them (including homosexuality) can be forgiven and cleansed "in the name of the Lord Jesus, and by the Spirit of our God."
