"Lazarus, come forth.... he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin" (John 11:43, 44). At that point Jesus commanded the onlookers to unbind him. One might ask, "Why didn't Jesus remove the stone with a show of power? Why didn't Jesus unwrap the revived corpse?" His response was a demonstration of the divine law of economy, namely, that we must do all we can, and when we have reached our limits, when we have asserted all our mental, moral and spiritual energies, then the powers of heaven will intervene. Man could remove the stone and unwrap the corpse, so he must do it, but only the power of God could call the dead to life. Accordingly, it was only the latter event that was divinely dictated. It is this same principle that governs out exaltation.
