Matthew 6:27 And which of you by worrying can add even one hour to his life? 6:28 Why do you worry about clothing? Think about how the flowers of the field grow; they do not work or spin. 6:29 Yet I tell you that not even Solomon in all his glory was clothed like one of these! 6:30 And if this is how God clothes the wild grass, which is here today and tomorrow is tossed into the fire to heat the oven, won’t he clothe you even more, you people of little faith? 6:31 So then, don’t worry saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?’ 6:32 For the unconverted pursue these things, and your heavenly Father knows that you need them. 6:33 But above all pursue his kingdom and righteousness, and all these things will be given to you as well. 6:34 So then, do not worry about tomorrow, for tomorrow will worry about itself. Today has enough trouble of its own.
