Mark - Exodus 19

God is all knowing. We live in a finite world where there is a beginning and an end. God doesn't have boundaries, before there was a beginning there was God. When God warns Moses to make sure the Israelites obey and not climb the mountain Moses seems taken aback. In his eyes he has followed the Lords' command but still the warning comes again. Why? Moses is human therefore his thoughts are based as such, God is so much more.
