All sin is ugly in Gods eyes and He cannot look on any of it. Sin is sin and the penalty is death. God doesn't say lying isn't so bad so you only get your hand smacked. We're to repent all of it. Daily. And being human, we sin daily. Even without knowing it.
But that isn't what this thread is about. The subject of the thread is diversity training and learning to accept sin as normal.
So I am going to bow out of the thread unless asked a question about "diversity".
All sin is sin, but the only one that is "unforgiveable" is the one against the Holy Spirit. I've thought about that quite a lot, and I think one thing it could mean is this idea of calling good bad and bad good. If you have managed to get yourself into a mindset where you are absolutely convinced that something that is wrong actually isn't, then I would suggest you have sinned against the Holy Spirit. That sin you commit cannot be forgiven, for the very simple reason that you don't accept that it is sin and therefore you will never call upon the Holy Spirit to redeem you from it. As you have said, God does not force us, even with things that would do us the utmost good. This is what really worries me about the modern Homosexual lobbies. It doesn't bother me that they commit sin (or rather it doesnt bother me more than anyone else committing any other sin) what I think is really frightening is this attempt to affirm that it is completely "normal". Now, I'm Ok with the intention behind diversity training as a principle, but if they are asking me to be tolerant of something that I think is absolutely wrong - I dont see how that can be justified. Would they accept diversity training in paedophilia? Or necrophilia? Or axe-murderer? Actually one day they might. Without a religious basis they don't accept any moral absolutes, so it all eventually comes down to what the majority are "comfortable" with.
