"Our fears are due to our failure to stir up - failure to think, failure to take ourselves in hand. You find yourself looking to the future and then you begin things and you say, 'I wonder what is going to happen?' And then, imagination runs away with you. You are gripped by the thing; you do not stop to remind yourself of who you are and what you are, this thing overwhelms you and down you go. Now the first thing you have to do is to take a firm grip of yourself, to pull yourself up, to stir up yourself, to take yourself in hand, and to speak to yourself...
You seem to be thinking about yourself and about life and all you have to do as if you were still an ordinary person. But...you are not an ordinary person! You are a Christian, you are born again, the Spirit of God is in you. But you are facing all these things as if you are still what you once were...and is not that the trouble with us all in this connection?
Though we are truly Christian, though we believe the truth, though we have been born again, though we are certainly children of God, we lapse into this condition in which we again begin to think as if none of these things had happened to us at all. Like the man of the world, the man who has never been regenerated, we allow the future to come to us and dominate us, and we compare our own weakness and lack of strength with the greatness of the calling and the tremendous task before us. And down we go as if we were but our natural selves."
