Keep a song in your heart.
Worry doesn't accomplish anything. It's in the Bible, Psalm 37:8, TLB. "Stop your anger! Turn off your wrath. Don't fret and worry—it only leads to harm."
There's no need to worry—God has everything under control. It's in the Bible, Matthew 6:31-33, TLB. "So don't worry at all about having enough food and clothing. Why be like the heathen? For they take pride in all these things and are deeply concerned about them. But your heavenly Father already knows perfectly well that you need them, and He will give them to you if you give Him first place in your life and live as He wants you to."
We cannot remove worry until we replace it with something better—prayer. It's in the Bible, Philippians 4:6-7, TLB. "Don't worry about anything; instead pray about everything; tell God your needs, and don't forget to thank Him for His answers. If you do this you will experience God's peace, which is far more wonderful than the human mind can understand. His peace will keep your thoughts and your hearts quiet and at rest as you trust in Christ Jesus."
Worrying is a waste of time. It's in the Bible, Luke 12:25-26, TLB. "And besides, what's the use of worrying? What good does it do? Will it add a single day to your life? Of course not! And if worry can't even do such little things as that, what's the use of worrying over bigger things?"
Give all your worries to the Lord. It's in the Bible, I Peter 5:7, TLB. "Let Him have all your worries and cares, for He is always thinking about you and watching everything that concerns you."
