The same God who created life in you can be trusted with the details of your life. MATTHEW 6:25: Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
Worrying about the future keeps you from doing your best today. MATTHEW 6:26: Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
Worrying is more harmful than helpful. MATTHEW 6:27: Which of you by taking thought can add one cubit unto his stature?
God does not ignore those who depend on him. MATTHEW 6:28-30: And why take ye thought for raiment? Consider the lilies of the field, how they grow; they toil not, neither do they spin: 29. And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these. 30. Wherefore, if God so clothe the grass of the field, which to day is, and to-morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?
Worry shows a lack of faith and of understanding of God. MATTHEW 6:32: (For after all these things do the Gentiles seek:) for your heavenly Father knoweth that ye have need of all these things.
