What does the Bible say happens to Homosexuals?
The exact same thing happens to homosexuals as heterosexuals. All are sinners, and all fall short of the glory of God (Romans 3:23). All must put their faith in Jesus, repent and be baptized in order to be forgiven of their sins. Homosexuals are no more sinful than heterosexuals and I assume that God will treat all fairly and alike.
It disturbs me when those who happen to be attracted to the opposite sex, but who have committed adultery or have engaged in premarital sex or who look at pornography (but of the opposite sex) or who have lustful feelings toward people to whom they are not married (but who happen to be of the opposite sex) feel they have a right to judge those who have the same kinds of feelings and actions, but toward the same sex. Clearly, all sin is horrible. All sin will be judged if not forgiven. One of those sins is judging others when we have a plank in our own eyes. I am afraid that many heterosexual Christians are guilty of violating Jesus’ command about judging (for example in Matthew 7:5)
Having said that, clearly sex outside of marriage between a man and a woman is sinful. Those who have lustful thoughts toward or about people to whom they are not legitimately marred to (and this legitimacy is only found in a marriage to one of the opposite sex, obviously) ought to be convicted about that personally and ought to repent of that personally, but to make the sin that others struggle with worse than our own is a kind of judgmentalism which is not acceptable in Christianity.
