The Bible consistently tells us that homosexual activity is a sin (Genesis 19:1-13; Leviticus 18:22; Romans 1:26-27; 1 Corinthians 6:9). Romans 1:26-27 teaches specifically that homosexuality is a result of denying and disobeying God. When a person continues in sin and disbelief, the Bible tells us that God “gives them over” to even more wicked and depraved sin in order to show them the futility and hopelessness of life apart from God. 1 Corinthians 6:9 proclaims that homosexual “offenders” will not inherit the kingdom of God.
God does not create a person with homosexual desires. The Bible tells us that a person becomes a homosexual because of sin (Romans 1:24-27), and ultimately because of their own choice. A person may be born with a greater susceptibility to homosexuality, just as people are born with a tendency to violence and other sins. That does not excuse the person choosing to sin by giving into their sinful desires. If a person is born with a greater susceptibility to anger / rage, does that make it right for them to give into those desires? Of course not! The same is true for homosexuality.
However, the Bible does not describe homosexuality as a “greater” sin than any other. All sin is offensive to God. Homosexuality is just one of the many things listed in 1 Corinthians 6:9-10 that will keep a person from the kingdom of God. According to the Bible, God’s forgiveness is just as available to a homosexual as it is to an adulterer, idol worshipper, murderer, thief, etc. God also promises the strength for victory over sin, including homosexuality, to all those who will believe in Jesus Christ for their salvation (1 Corinthians 6:11; 2 Corinthians 5:17).
