I'm looking at his from a biblical perspective...
God gave us humans urges which he instilled at us from birth. Some are good, some are bad.
Psa 139:13
For you created my inmost being; you knit me together in my mother's womb.
Some of us have been created with major disadvantages
.
Exodus 4:11
And the LORD said unto him, Who hath made man's mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD?
John 9: 1-3
And as Jesus passed by, he saw a man which was blind from his birth. And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind? Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him.
The above verses talk of physical limitations, but the bible also shows us that God instills in us other disadvantages as well.
Isaiah 45:7
I form the light and create darkness. I make peace and create evil. I the Lord do all these things.
For many of us, we see some of these urges as immoral or even evil. But God put them in all of us. Most of us he made heterosexual. Some of us he made homosexual. The one thing we all have in common is God expects us to repress those sides of our nature. We have the urge to have heterosexual sex (it's in our DNA), but we’re not allowed to have pre-marital sex or commit adultry. We have the urge to punch someone who angers us, but we’re not allowed to do that. You want to have sex with a member of the same sex? It’s still a no-no. God has given us all different challenges to over come.
God expects you to repress your homosexual tendencies. If not. Well you can look to the bible for the consequences.
Is this fair that God should put some of us through cruel games and not another? Of course not, but God is God and he makes the rules. It’s his game and we have to play by his rules whether we like it or not. Some of us have bigger challenges to overcome than others, but that's the way it is. We are not permitted to be what God created us as. We are expected to fight against our human natures. If we don't play by his rules and we don't overcome his challenges, then we suffer the consequences.
