I see from your posts that you have a good heart and that you are kind and empathetic towards those who suffer....you too have suffered much it seems. But sin is in evidence even in homosexuality. It is true that this is a genetic pre-disposition that these ones cannot help. God does not condemn them for it even as he does not condemn the man with the deformity. He teaches us to live happily in spite of these impairments.
Homosexuality has been around as long as sin has existed, but it doesn't excuse individuals from engaging in conduct that to God is 'unnatural'. Sex is for procreation....we see this in just about all species of living things on this planet.....it is designed to produce offspring.
God only authorizes sex between a man and a woman in scriptural marriage. He is not one bit interested in how a person justifies sin, where the use of one's reproductive parts are concerned. The act of copulation is a sacred one, only to be sanctioned within the bonds of marriage, which was intended to be the basis for a new family. Homosexual couples cannot reproduce without the aid of a third party, which is technically adultery if the egg or the sperm come from someone other than one's marriage mate. Since scriptural marriage can never be applied to homosexuals, then their union will never be legitimate in God's eyes, regardless of what man's laws dictate. Christians cannot be practicing homosexual acts if they desire God's blessing. No Christian can be immoral in their conduct, regardless of gender.
God will put in every effort if he sees genuine love in the heart of a person who wants to put God's rules before selfish desire. He is ready and willing to help anyone to live a good Christian life free from deliberate sin. Many heterosexuals never find a marriage mate, and learn to live celibate lives. Any sexual activity outside of marriage is "fornication" and this carries the death penalty in the Bible.....its that serious. Homosexuals are not exempt. Sin is only part of this life....a brief encounter when you compare it to the eternity of peace and happiness that is promised to the loyal ones who keep God's commands even when that is difficult.
You only see yourself as kinder if you don't understand the reasons for the present situation...and who is really to blame for them. We cannot blame God when it is the devil who is responsible for all our woes.
This life is a demonstration of what happens when humans want to do things their way.....nothing good comes of it and the result fights with the life we want to live. We know we are designed to live a very different life....one that God will give us in the new world to come. (2 Peter 3:13)
God wants to grant all people the desires of their heart....but only when such desires conform to his righteous standards.
He doesn't want humans to take things for themselves without his permission, but to wait patiently until he has concluded his test period and then see the results of his blessings, which will be beyond our wildest imaginings.
