But you seemed to miss some of the verses before that, which say,
19 "Because that which may be known of God is manifest in them; for God hath shewed
it unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made,
even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified
him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things."
This is more about idol worship than sex. And it is BECAUSE they were worshiping idols, “Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:”
Now the questioner asks, have YOU ever had an idol in your life? Worshiping mammon, or cars, or civil liberties, or the "right" spouse, or the "right" church? Maybe looking for the best job, car, piece of jewelry, bank account, food, drink, children, etc? Why, then, because YOU have had such an idol in your life, why are you not homosexual?
Could it be that it is NOT a choice?
