Matthew 6:24-34
"No man can serve two masters. He will either hate one and love the other or be attentive to one and despise the other. You cannot give yourself to God and money. I warn you, then: do not worry about your livelihood, what you are to eat or drink or use for clothing. Is not life more than food? Is not the body more valuable than clothes?"
"Look at the birds in the sky. They do not sow or reap, they gather nothing into barns; yet your heavenly Father feeds them. Are not you more important than they? Which of you by worrying can add a moment to his life-span? As for clothes, why be concerned? Learn a lesson from the way the wild flowers grow. They do not work; they do not spin. Yet I assure you, not even Solomon in all his splendor was arrayed like one of these. If God can clothe in such splendor the grass of the field, which blooms today and is thrown on the fire tomorrow, will he not provide much more for you, O weak in faith! Stop worrying, then, over questions like, 'What are we to eat, or what are we to drink, or what are we to wear?' The unbelievers are always running after these things. Your heavenly Father knows all that you need. Seek first his kingship over you, his way of holiness, and all these things will be given you besides. Enough, then, of worrying about tomorrow. Let tomorrow take care of itself. Today has troubles enough of its own."
