scripture

do not be anxious

'Therefore, I tell you, do not be anxious about your life, what you shall eat or what you shall drink, nor about your body, what you shall put on. Is not life more than food, and the body more than clothing? Look at the birds of the air; they neither sow nor reap nor gather into barns; and yet your Heavenly Father feeds them. Are you not of more value than they? And which of you by being anxious can add one cubit to his span of life? And why are you anxious about clothing? Consider the lilies of the field, how they grow; they neither toil nor spin; yet I tell you, even Solomon in all his glory was not arrayed like one of these. But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, o men of little faith? Therefore do not be anxious, saying, "What shall we eat?" or "What shall we drink?" or "What shall we wear?" For the Gentiles seek all these things; and your heavenly Father knows that you need them all. But seek first his kingdom and his righteousness, and all these things shall be yours as well.' (Matthew 6.25-33)

everything is indeed clean

Do not, for the sake of food, destroy the work of God. Everything is indeed clean, but it is wrong for any one to make others fall by what he eats; it is right not to eat meat or drink wine or do anything that makes your brother stumble. The faith that you have, keep between yourself and God; happy is he who has no reason to judge himself for what he approves. But he who has doubts is condemned, if he eats, because he does not act from faith; for whatever does not proceed from faith is sin. (Romans 14.20-23)
