Anxiety is a terrible thing. It is a state of uneasiness and worry, of fearfulness and dread. But prayer can make it all go away; when you pray God will help you to see that He is in control and that He loves you and cares for you.
When we are anxious, we think only of ourselves and of all the things we think we need. Prayer, however, will take us to God and draw us away from ourselves so that we are more concerned for His kingdom and His righteousness. The practice of prayer will help us to see that life is more than food and clothing, and that we have no need to worry about those things—since God cares for us just as he cares for little birds and flowers (Matt. 6:25-29).
If you are prone to anxiety, try to develop the habit of praying about everything. And when you pray, instead of lingering in your anxiety, focus instead on God, honoring Him with thanksgiving and praise (Rom. 1:21). As you pray with thanksgiving, taking all of your concerns to God, He will fill you with an incredible peace. Here is the promise from Philippians 4:6-7:
Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus.
