I've held the hands of a gay man who tried therapy, counseling, shock treatment, testosterome, religious counseling, Ex-Gay ministries, forcing female interaction (and he was a handsome man), and moving from place to place in his 50+ years...and he was sitting there crying his eyes out, begging God to change him, that he was meeting God halfway, and God never showed up to help him the rest of the way. In that moment, it was impossible for me to agree this was a "lifestyle" and a "choice" for this man who so desperately wanted to change, and tried everything he could. That man exists.
The main problem with those who reject God's revealed truth because God does not change them don't understand that homosexuality is at it roots relational, not sexual or physical. It is possible to live a celibate life and still interact with other members of the same sex on a non-sexual basis. The real stumbling block is human's want a life free of struggles, which ignores what Jesus taught.
John 16:32-33
32 "Behold, an hour is coming, and has already come, for you to be scattered, each to his own home, and to leave Me alone; and yet I am not alone, because the Father is with Me. 33 "These things I have spoken to you, that in Me you may have peace. In the world you have tribulation, but take courage; I have overcome the world." NAS
He also taught:
Luke 18:28-30
29 And He said to them, "Truly I say to you, there is no one who has left house or wife or brothers or parents or children, for the sake of the kingdom of God, 30 who shall not receive many times as much at this time and in the age to come, eternal life. " NAS
Experts agree that sexuality is determined no later that ages 7-9, which is before puberty. The optimum time to deal with homosexual desires is during puberty, however the political religious right and rabid gay activists refuse to show compassion on the youth of our country in an attempt to push there own political agenda's. And then there are those who feel that God created some to be gay, which is a perversion of God's revealed truth.
