Homosexuality is referred to many times in the Bible, some of which you may be aware. In the Old Testament, Leviticus 18:22 it says, “You must not have sexual intercourse with a male as one has sexual intercourse with a woman; it is a detestable act.” (New English Translation). (The reason the Old Testament is cited in this manner is because this is a moral aspect of the old law. The moral aspects are based upon God who does not change. What God “detested” in the OT he detests in the New Testament.) Likewise, in Romans 1:26-27 Paul notes that homosexuals have abandoned their natural sexual relationship for an unnatural one. (Side note: Darwinistic Evolution struggles with a reasonable explanation as to why homosexuality occurs in nature; as it is counter-productive to natural selection.) Then also in 1 Corinthians Paul makes a point about homosexuality that isn’t quite understood by seculars in the Christian/Homosexual dialog.
1 Corinthians 6:9-11 (NET) says, “Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived! The sexually immoral, idolaters, adulterers, passive homosexual partners, practicing homosexuals, thieves, the greedy, drunkards, the verbally abusive, and swindlers will not inherit the kingdom of God. Some of you once lived this way. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.”
The point is that Paul makes is Christians don’t view homosexuality as different as any other sin. They are all morally reprehensible in God’s eyes, and for the Christian that means conforming their lives to what God asks of us (not unreasonable). It’s not like homosexuality is a special sin to Christians, we are just as against pride, sex outside of marriage, greed, hatred and jealousy (for example) as we of homosexuality. It’s all sin! God has nothing to do with sin; sin disqualifies you from Heaven and fellowship with God. James wrote in James 2:10, “For the one who obeys the whole law but fails in one point has become guilty of all of it.” James is saying by committing that one sin makes you just as guilty as someone who has committed thousands of sin. You are both equally in need of forgiveness from your sin. That forgiveness can only come from turning from that sin (whatever it is) towards Christ.
Homosexuality is difficult to handle today not because the truth is difficult to understand but because of how Christians have historically handled the issue. Over the past decades Christians have, in my opinion, misbehaved in their approach towards Homosexuals. Instead of trying to win them over to Christ with love many engaged in persecution and shunning of homosexuals. That, in turn, was counter-productive and has spawned a lot of hate from the homosexual community towards the Christian community. Even some Christians still don’t understand that it’s not about winning the argument; it’s about winning the soul.
