The greatest difficulty in the Christian life is to get to the place where one is prepared to admit that the whole thing is too big for him, and that the power of the enemy is too great for him, and if his Jericho is to fall, then, somehow, God must bring it about. I believe that before God entrusts any of His people with a real measure of spiritual power, victory, and blessing, He brings them to a place from where they have surveyed Jericho so long that they have come to see that its conquest is absolutely hopeless. God expects nothing more from us than failure, yet we spend years trying to make ourselves something other than a failure. So long as we think we can do it alone, the omnipotent resources of God in Jesus Christ our Risen Lord cannot help us.
