I have to set this up, so bear with me.

Having a discussion with someone the other day about politics and religion (yeah I know). My basic position is government has been established by God, and we should follow it's rules, as long as those rules don't go against God's law. As such, I cannot vote for a democrat because they think abortion is ok, and it's clearly against Gods law. So this person goes, what about birth control. God knows everyone before they are even created. It seemed like this person was likening using birth control to abortion, and went on to say he would meet all his unconceived children in heaven.

I just cannot get there. Just because you have sex doesn't mean conception occurs. I can't find a biblical basis for his position.

Thoughts?
