There are biblical warnings to deter mankind from indulging in homosexuality. Leviticus 18:22 clearly warns against men indulging in sexual relationships with other men, and what God thinks about it. It reads, 22) You shall not lie with a man as with a woman; it is an abomination.
The Apostle Paul, writing in his letter to the Romans, is even clearer, for he not only warns men and women about the practice of homosexuality and lesbianism, but he points out it is against nature, and that there would be terrible consequences for those ardently committed to this lifestyle. Romans 1:26-27 says:
26) For this reason God gave them over and abandoned them to vile affections and degrading passions. For their women exchanged their natural function for an unnatural and abnormal one,
27) And the men also turned from natural relations with women and were set ablaze (burning out, consumed) with lust for one another--men committing shameful acts with men and suffering in their own bodies and personalities the inevitable consequences and penalty of their wrongdoing and going astray, which was [their] fitting retribution.
Amazingly enough, and in spite of all the evidence to the contrary, there are clerics today--false prophets, as it were--who say the Bible does not repudiate homosexuality. When Jesus was threatening a group of religious hypocrites, and said to them it was going to be worse for them than Sodom and Gomorrah, all those of the Jewish culture understood and knew of the destruction of Sodom and Gomorrah, which was destroyed by "fire and brimstone," and why it was destroyed.
As Christians, should we suppose and can we believe that all of a sudden, God has changed his perspective on homosexuality as these false prophets would have us believe? Are we that stupid? Remember, Jesus said in the last days it would be as the days of Lot.
So, what was it like it the days of Lot? Homosexuality was demanding and imposing itself upon the righteous to capitulate, to yield, to give way to its predominance where Lot lived. Genesis 19:1-5 says:
1) It was evening when the two angels came to Sodom. Lot was sitting at Sodom's [city] gate. Seeing them, Lot rose up to meet them and bowed to the ground.
2) And he said, My lords, turn aside, I beg of you, into your servant's house and spend the night and bathe your feet. Then you can arise early and go on your way. But they said, No, we will spend the night in the square.
3) [Lot] entreated and urged them greatly until they yielded and [with him] entered his house. And he made them a dinner [with drinking] and had unleavened bread which he baked, and they ate.
4) But before they lay down, the men of the city of Sodom, both young and old, all the men from every quarter, surrounded the house.
5) And they called to Lot and said, Where are the men who came to you tonight? Bring them out to us, that we may know (be intimate with) them.
