The Bible says that we are to present our bodies "as living sacrifices, holy and pleasing to God." Of course, if you give your body, you give everything it contains. That means giving yourself wholly to God, and the idea of giving yourself wholly to God contains three laws.
The first law is the law of surrender. If you do not surrender, it will be totally impossible for the Lord to do anything for you. Surgeons have to have the surrender of their patients. If I went to a surgeon and insisted that I was going to tell him how to do the job and not only that but stay awake and resist him, the surgeon could not work. It would be impossible. Surgeons must put their patients to sleep so they cannot resist, so they are in a state of surrender. That is the law of surrender. A more beautiful and biblical description is the story of the potter and the clay, which illustrates the law of surrender further. The potter has soft, yielding clay, but if the clay does not surrender, the potter cannot do a thing with it. If there are burnt places, hard places or unsurrendered places in the clay, though the potter be a genius in making vessels, the artist still could not make anything useful and beautiful out of an unyielding blob of clay. It is possible for an object to be useful but not beautiful, like a garbage can. It is also entirely possible to be beautiful and not useful, like the lily. The lily has no utilitarian place in the world. It is possible to have a vessel that is useful without being beautiful. The old cream crocks in our spring house on the farm were useful all right. You could pour the milk in them, wait for the cream to rise and skim it off. They were not beautiful, but they were quite useful. Everybody has in their home beautiful little knickknacks. They are utterly useless, simply to be enjoyed for their beauty. But God wants His vessels to be both useful and beautiful. If God is going to make those kinds of vessels out of us, however, we are going to have to yield to the law of surrender. Give yourself to God as a living sacrifice and let Him have you--all of you.
You turn things upside down, as if the potter were thought to be like the clay! Shall what is formed say to him who formed it, 'He did not make me'? Can the pot say of the potter, 'He knows nothing'? Isaiah 29:16
Give yourself as a living sacrifice. That means living day by day on the altar. Sacrificial animals were killed then offered. No getting off the altar. Are we living on the altar or off of it?
Lord, here I am. I give myself to You. O God, help to stay on the altar and not to slip off.
