Repentance

Proverbs 18:5 NRSV
It is not right to be partial to the guilty,
or to subvert the innocent in judgment.

What is wrong with homosexuality?

A whole lot of things, but mostly this: It's an abomination to God. He said this not once, not twice, but several times...and it wasn't all in one breath, but was spread out over 1,500 years. In the beginning, God created man and then He created a woman to be man's helpmate. I imagine that if God had thought homosexuality was okay, then he would have created another man...or just two women. But He didn't, so that's the beginning.
