Worry prevents God from helping you

He knows that we are going experience anxiety. Why else do you think He gives us instructions for how to manage it?

Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God’s peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus. (Philippians 4:6-7)
