1 Peter 5:7 says that we should be casting all your anxiety on Him, because He cares for you. This casting is not a passively handing or gently tossing action. It is forcefully throwing all the anxiety of my day, week, or life on Him. Why? Because He is going to do all the caring for me! I can roll it all over onto Him and let Him do my worrying. Now of course it is only worrying when we are carrying our own load and trying to find our own way in the midst of the struggle. For God, it's not worry at all. He is literally caring for us.
I hope you can see this picture. It's not just that He cares for us in the sense that He has great concern over the matters that are concerning us. Of course He loves us, tends to us and carries us...but in this sense, when we can roll all of the things that concern us, all of the things that cause us anxiety over onto Him - then He will do the caring... so we won't have to!
Make today a day when you hand it all over to Him and you do not worry about stuff at all! It's like having a day off emotionally. Let Him do the caring for you today! I think I will try it again tomorrow too!
