Matthew 6: 31 - 34
31 Therefore do not be anxious, saying, `What shall we eat?' or `What shall we drink?' or `What shall we wear?'
32 For the Gentiles seek all these things; and your heavenly Father knows that you need them all.
33 But seek first his kingdom and his righteousness, and all these things shall be yours as well.
34 "Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Let the day's own trouble be sufficient for the day.
