Suppose there is a living God, a God that made everything.

Suppose that that God dislikes certain activities -- like any homosexual act.

Suppose that God made a horrible example of some people who constantly performed such acts.

Would you think the horrible example was just to punish the evil doers?

Would you think it was to teach others that such behavior was not good, even dangerous, and that one should not do it at all, ever?

Would you think that God had no right to do that?

Well, whatever you would think, you might read from Genesis 18:16 to the end of Genesis 19.

I think that says that whatever God hates he will destroy, and that we better be careful that we don't do anything that he hates.

You, of course are still free to have your own moral code, but if your code is not God's code you might find yourself in trouble.
