Faith v Knowledge.

There seems to be a popular notion today: How can God fault someone for not believing when God never revealed himself to them? It is certainly within an all powerful, all knowing, all good God to prove to everyone beyond any doubt that he exists.  But if that is what it takes for someone to believe in him, they aren't a very good believer are they?  What great thing have they done if they have faith in God only after God appeared to them? At that point people would have knowledge, not faith.  Giving everyone firsthand knowledge isn't something God wants to do.   It would be like having a police officer is standing right next to us 24/7. If that's what it takes to make us obey the law, we aren't very good are we?   Faith is what God is after not knowledge,  he already knows everything.
