Is there anything that you can do to fix whatever the problem is? If so, then fix it and move on. If you can’t fix it then find someone who can and give the problem to them. If the problem happens to be something which no person can fix, then give it to God and leave it in His hands. He can take care of all of your problems whether they are lost keys, a test at school tomorrow, an illness which can’t be cured by human efforts or just a soul that is hurting in some way that can’t be fixed by any human hand…but God can. Worry is something that we do when we can’t find a fix for something but we don’t trust God enough to let Him have it long enough to fix it His way.
God can always find a way to fix our problems because He knew the way to fix it before you ever asked Him to help you with it. Sometimes we don’t like the way He does it or maybe even the time that He takes to fix it, but His way is always the best way. So, give your problems, whatever they may be, to Him and move on to tomorrow and the next day. He’s got it handled no matter what it may be.
Matthew 6: 25-34 is where Jesus tells His disciples this:
Do Not Worry
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. Is not life more than food, and the body more than clothes? 26 Look at the birds of the air: They do not sow or reap or gather into barns—and yet your Heavenly Father feeds them. Are you not much more valuable than they? 27 Who of you by worrying can add a single hour to his life?c
28 And why do you worry about clothes? Consider how the lilies of the field grow: They do not labor or spin. 29 Yet I tell you that not even Solomon in all his glory was adorned like one of these. 30 If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the furnace, will He not much more clothe you, O you of little faith?
31 Therefore do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For the Gentiles strive after all these things, and your Heavenly Father knows that you need them. 33 But seek first the kingdom of God and His righteousness, and all these things will be added unto you.
34 Therefore do not worry about tomorrow, for tomorrow will worry about itself. Today has enough trouble of its own.
