You will never exhaust God with your worries. You will never reach the end of his ability to hear or handle your fears. You will never disappoint him with the amount of times you cast your anxiety on him. Why? Because he cares for you, he cares for me, he cares for us!
I Peter 5:7 Putting all your troubles on Him, for he takes care of you. [BBE]
I Peter 5:7 Casting all your anxiety upon Him, for he careth for you. [ASV]
