"Therefore I say to you, do not worry about your life, what you will eat or what you will drink; nor about your body, what you will put on. Is not life more than food and the body more than clothing? Look at the birds of the air, for they neither sow nor reap nor gather into barns; yet your heavenly Father feeds them. Are you not of more value than they?"
Given the context of the preceding verses, Jesus is telling us that if God is first in our giving, then He indeed has our heart. If He has our hearts, He can guide us and meet our needs, and we have no need to worry about provision for our life.
He feeds the birds. He will take care of you. Do not worry. Obey Him, trust Him, and look to Him for your daily bread.
"But seek first the kingdom of God and His righteousness, and all these things shall be added to you."
