Do not worry about your life, what you will eat or drink; or about your body, what you will wear....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?....So do not worry....But seek first his kingdom and his righteousness, and all these things will be given to you as well. 
Matthew 6:25, 23, 31, 33
