"Cast your cares on the LORD and he will never let the righteouse be shaken." - Psalm 55:22
Worry can fill all the hours of our days if we let it. Even when we try our best to let go of those doubts and fears, we can find them creeping into our thoughts. When that happens, remind yourself that you're not alone. Give those thoughts to God one by one and remind yourself of his promise that you can never be shaken.
