Teaching children to give all their worries to God (Matthew 6:25-34).
Teaching and showing children that God loves them and takes care of them.
Look at the birds, how God cares for them: feeds them, gives them a nest, how beautiful He clothes them! If our Father, God, cares so much for the birds, then how much more will He take care of us, His children! So do not worry what you will eat, drink, what you will wear. Place All your cares and worries on God, He loves us!
In Matthew Chapter 6, it is written:
25 “Therefore I tell you, do not worry about your life, what you will eat or drink, or about your body, what you will wear. Isn’t there more to life than food and more to the body than clothing? 26 Look at the birds in the sky: They do not sow, or reap, or gather into barns, yet your heavenly Father feeds them. Aren’t you more valuable than they are? 27 And which of you by worrying can add even one hour to his life? 28 Why do you worry about clothing? Think about how the flowers of the field grow; they do not work or spin. 29 Yet I tell you that not even Solomon in all his glory was clothed like one of these! 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? 31 So then, don’t worry saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?’ 32 For the Gentiles pursue these things, and your heavenly Father knows that you need them. 33 But above all pursue his kingdom and righteousness, and all these things will be given to you as well. 34 So then, do not worry about tomorrow, for tomorrow will worry about itself. Today has enough trouble of its own.”
