But others hadn't seen what Moses had seen. Moses learned the hard way that the leader must live in a manner consistent with the character of Christ. The sin of Moses was two fold - he didn't reverence God, and he didn't trust God. We can learn some great lessons from Moses' failure. First, never lead from a position of unbelief.
Leadership requires faith.
God will continuously place impossible situations before us. If we want to go in and conquer a land promised to us, then we must trust completely in Him. Faith and victory go hand in hand. Second, we must lead people from the heart of humble reverence of Christ. The disciples were simple men and women who had been with Christ.
