God says, "Do not be anxious about ANYTHING."
But, with EVERYTHING that would even slightly worry you, there is a solution. God says, "Just ask me to resolve your situation."
But, when you ask God, your request must come with thanksgiving. What does that mean? It means that you ask God fully believing he will keep his promise. You even thank him in advance for the solution. Thank him in advance for the peace that he will bring. The prayer offered in faith will make the difference!
