It's a lot easier to trust in someone once you get to know them. Trusting in the Lord allows our Faith to be used more effectively, simply because once you know the Lord's nature and character, you realize there is no reason to doubt what He has promised us. When doubt, unbelief and fear have all been removed, all that is left is pure Faith. That's when the mountains you're speaking to begin to move!
