Modern science says that homosexuality is congenital, where reasons are either hereditary or connected to progress of individuals. This claim is very easy to cancel. If homosexuality would be congenital, so people couldn't get rid of it. Many former homosexuals have forsaken homosexuality and became heterosexuals after they have become Jesus' disciples. These testimonies show for us that homosexuality is not congenital, but a sin.

Many scientists believe that homosexuality is genetic, congenital, a matter and orientation that can't be changed as heterosexual.  The paradox is that many scientists don't believe in God of the Bible, and they proclaim that God of the Bible doesn't exist. Nevertheless, God of the Bible is capable to change homosexual individuals to be as heterosexuals.

Even if you don't believe the Bible, so homosexuality is against the natural order. This can be proven very clearly.

If we put gay men to the deserted island, so they would soon become extinct, because they cannot have children.

If we put lesbians to the deserted island, so they would soon become extinct, because they cannot have children.

If we put to the third island heterosexual men and women, so the life continues on this island and new generations born and continued living. Heterosexuality is the natural order, in which the life goes on from birth of the new generations.  

It is very clear that homosexuality is not according to the natural order, but against the natural order. Preceding examples cancel also all discrimination speeches against homosexuals. In the question is not discrimination of homosexuals, but the fact that homosexuality is against the natural order of the life.

Defenders of homosexuality say that in the nature appears homosexuality activity between animals. It is true that in the life of animals appears homosexuality, but it doesn't cancel the natural order.

Ro 8:
19 For the earnest expectation of the creature waiteth for the manifestation of the sons of God.
20 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.

The Bible says that the whole creation suffers from the bondage of corruption (sin). Animals also kill other animals as people also kill other people. God didn't create animals to kill one another, and neither that people would kill one another.

Because of bondage of corruption also in the animals' world and in the world of people are homosexuality, but it is not the natural order. It is natural that men and women sex organs are perfectly suitable practicing sex and having descendants. This proves that homosexuality is against the natural order. The science has stepped to the deep aberration, claiming that homosexuality would be congenital, what it is not according to preceding clear evidence.

The science tries to convince homosexuality as congenital claiming that there exist gay gene. This claim is not true. Many former gay men have forsaken homosexuality and turned heterosexuals when they have believed in the Lord Jesus. In these cases, what would happen to genes that would be encoded as gay genes?  Does gay gene change into a heterosexual gene? If there exist gay gene, so it would mean that you couldn't forsake your identity. The gay gene information is false information, because many ex-gay men have turned heterosexuals after they have believed in the Lord Jesus. This evidence disproves and overrules perfectly theory of a gay gene.

Hypothesis about a gay gene is developed for the reason to support sin by the scientist who doesn't believe in God of the Bible. The Lord Jesus prophesied that in the last days the world lives like in Sodom also accepting sin of homosexuality. Modern science is helping to fulfill Jesus' prophecy by scientists false information.

There are also good science and truthful science, but gay gene information is false information, in which preceding examples annulled completely.
