We must not allow our thoughts to make us powerless. If we do not cast our worry upon the Lord then doing it on our own will bring worry and anxiety. I use to worry all the time. Worry about bills, next meal, marriage situations, etc. But once I allowed God to take control of what I can't control, it helped me be more humble. And it gave me peace because I know my God is handling it for me. God and his word is the sauce of cure to overcome it all.
