When we worry “We are taking upon ourselves the responsibility that belongs to God, and thus are really putting ourselves in His place. We may well have anxiety and anticipate danger and loss, for it is certain to befall us. But when we really believe that God loves us and means to do us good, we shall cease to worry about the future.” – Mind Character and Personality p. 468
God does not condemn prudence and foresight in the use of the things of this life; but the feverish care, the undue anxiety, with respect to worldly things is not in accordance with his will.— Counsels on Stewardship, 159.
