“Jesus knew that … he had come from God and was returning to God.” John 13:3
Jesus’ coming to earth was for a very specific purpose. When Jesus hung on the cross he said, “It is finished”, because He had achieved His purpose. He had done everything necessary to provide us with salvation. If we try to add something to our own salvation we are saying Jesus’ death wasn’t enough.
If someone unexpectedly knocks on our door at Christmas and gives us a gift, we don’t consider that we have contributed to the visit by opening the door or accepting the gift. Something similar happens when God knocks on the door of our heart and offers us the gift of salvation. We open the door and accept the gift, yet we have not contributed.
Selwyn Hughes (in EDWJ 6/10) writes, “There is something about human nature that makes us want to do something to remedy our spiritual deficiencies rather than trust in the grace and power of God.” But there is nothing to do because Jesus has already done it. He has done everything necessary to save us and sustain us.
Mostly we hate to feel helpless, nevertheless we must come to God on his terms with empty hands and a humble heart. This is the theme of the hymn Rock of Ages by Augustus Toplady which contains these words:
“Nothing in my hand I bring;
Simply to Thy Cross I cling!
Naked, come to Thee for dress;
Helpless look to Thee for grace.”
