Have you seen the picture depicting an image Jesus with a little girl holding a teddy bear asking her to give it up? It shows Him holding a bigger bear behind his back that she can't see. This is a very good illustration of how we need to give everything over Him. I'm not just talking about our possession, though we need to do that too, I'm talking about everything we cherish in our hearts. Give Him EVERYTHING! Imagine the things you value most in the hands of God. He created all that we see from a little dirt and water, I'm sure He can handle a few of your measly things. Trust Him. He is our creator, our most Holy Father who only wants the best for His children. We tend to want to hold on with a tight grip but if we lift those things up to the Lord He will take special care of them and throw out what we really don't need. If we give everything over to Him, what then will we have to worry ourselves with?
Cast your burden on the LORD, and he will sustain you; he will never permit the righteous to be moved. Psalms 55:22
