That's powerful stuff!
I'm a worrier.
I have passed it down to my kids and their kids are doomed! As I've grown older, I don't worry as much and you could even say, I have been cured from chronic worry. It has nothing to do with me. It has everything to do with my loving God. These verses say it better than I could ever say it.
God has shown me time and time again that he loves us, would do anything for us, and protect us from the worst enemy. We have no reason to worry. Praise God that he can heal us from our deepest sicknesses, even the ones in our minds and our hearts. Worry is a sickness just like any other disease. It can eat away at us and eventually affect our families, friends, coworkers, and ministry partners. If we let it, it will devour us just like a cancer or a severe infection. The only healer is Jesus and turning over our cares to his loving mercy and grace. I wish I had known this 30 years ago. I would have probably added more hairs to my head and years to my life!
