All in Lean on God

Are we a people who begins our confrontation with trouble by leaning on the Lord for help, but who over time begins to waver in our faith? Are we like the Israelites who trusted in God for their protection in the wilderness only to lose hope when the armies of Pharaoh were approaching, and their backs were against the sea? How steadfast are we, and how firm is our grasp on the promises of our Father?
