"Matthew.2667":
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?
Matthew 6:25 (Agnes) May 92' IICS-SLU B.C.
