I wasn't aware libertarians reject God,I thought they leave it up to the individual;and said individual is still held reponsible for his acts and their consequences.
libertarians don’t necessarily. I can’t speak for Libertarians, though. I’m not a registered Libertarian, nor do I know much about their platform. I just believe in the libertarian foundation of this country and nation.
The problem with libertarians (and this isn’t true for all libertarians) is the tendency for idolatry. When you worship liberty as the “summum bonum”, it may not be a conscious rejection of God, but it amounts to the same thing.
