The Bible provides God's blueprint for marriage and for His good gift of sex in Genesis 2:24. The gift is only to be enjoyed within a marriage between a man and a woman.
There are no exceptions suggested, such as homosexual partnerships. From Genesis on, the Bible praises the marriage of a man and a woman, but it speaks only negatively of homosexual behavior whenever it is mentioned.
The Old Testament states, "Do not lie with a man as one lies with a woman; that is detestable" (Leviticus 18:22 and 20:13). The New Testament agrees, listing "homosexual offenders" among a list of people who "will not inherit the kingdom of God" unless they are cleansed through Christ (1 Corinthians 6:9-11).
Other passages are Genesis, chapter 19; Romans 1:18-32; 1 Timothy 1:8-11; and Jude, verse 7. However, it is important to note that the Bible speaks only of homosexual behavior (which would include lust—choosing to fantasize about behavior), not unchosen feelings. God will not judge a Christian guilty for his or her involuntary feelings.
Sometimes it is said that the Bible does not record any words of Jesus about homosexuality, and therefore it must be acceptable to God. However, the Bible does not record sayings of Jesus about a number of other specific sins either. When people asked Jesus about marriage, He told them to remember what Genesis said about God's plan for marriage (Matthew 19:1-12). So, in this sense, Jesus did have something to say about homosexual partnerships. God only blessed sex within the committed marriage relationship of a man and a woman.
Some have tried to reinterpret what the Bible says, in an effort to approve homosexual relationships. For a reply to such efforts, read "Straight and Narrow" by Thomas Schmidt or "A Strong Delusion" by Joe Dallas.
