"Is there then anything you will not leave for Christ? You cannot know him - and yet he is the Truth, the one thing alone that can be known! Do you not care to be imperfect? Would you rather keep this or that, with imperfection, than part with it to be perfect? You cannot know Christ, for the very principle of his life was the simple absolute relation of realities; his one idea was to be a perfect child to his Father. He who will not part with all for Christ, is not worthy of him, and cannot know him; and the Lord is true, an cannot acknowledge him ... "

"Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Who of you by worrying can add a single hour to his life?

"And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. Yet I tell you that not even Solomon in all his splendor was dressed like one of these. If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own."
