Have you realized that most of your unhappiness in life is due to the fact that you arelistening to yourself instead of talking to yourself? Take those thoughts that come to you the moment you wake up in the morning. You have not originated them, but they start talking to you, they bring back the problems of yesterday, etc.
Somebody is talking. Who is talking? Your self is talking to you. Now (the Psalmist’s) treatment was this; instead of allowing this self to talk to him, he starts talking to himself. ‘Why art thou cast down, O my soul?’ he asks. His soul had been depressing him, crushing him. So he stands up and says: ‘Self, listen for a moment, I will speak to you.’
The main art in the matter of spiritual living is to know how to handle yourself. You have to take yourself in hand, you have to address yourself, preach to yourself, and question yourself. You must say to your soul: ‘Why art thou cast down’– what business have you to be disquieted?
You must turn on yourself, upbraid yourself, condemn yourself, exhort yourself, and say to yourself: ‘Hope thou in God’– instead of muttering in this depressed, unhappy way. And then you must go on to remind yourself of God, who God is, and what God is, what God has done, and what God has pledged Himself to do.
