It's crazy that the children of Israel would find themselves in this position, just over a year removed from the greatest event in their life-time, the first passover. God has done so much for these people and yet they still have no faith that their God can overcome enemy armies, fortified cities and the dreaded descendants of Anak.
It sounds so silly, but we still do the same thing today. God is mighty, God is strong, and God is able. If we'll just follow His voice through the unknown. God will provide.
