Psalm 23:1 “The Lord is my shepherd, I shall not want.”
Do unfinished or incomplete things bother you? Maybe it’s a set of encyclopedias that is missing a couple volumes. Or perhaps you’ve seen a house that has stood there partially constructed for years on end. Whatever it is, it is likely a mark of us being made in the image of God that causes us to have negative reactions to unfinished or incomplete things. You see, God is a finisher. He never does anything part way. He is complete in His being. When he provides, he provides everything we need. His Word is complete, perfect in the sense of nothing missing. Jesus said that nothing in his Word would ever pass away. But we, in that we are all flawed by a sinful, fallen nature, are incomplete in our natural condition. We’ve “missed the mark,” which is another way of describing sin. There is an emptiness in us. We have unfulfilled needs. We are unsatisfied. We lack. And even when we think we don’t need a thing, we think that way because we are so lacking, being blind to our own spiritual condition much of the time (Revelation 3).
God, on the other hand, is complete in his nature. He lacks nothing. He is perfect, complete, whole. His very nature is “fullness.” It is the fulfillment that comes to a person who believes in Christ that is one way to describe what it means to be a Christian. It is at the moment of salvation that the believer experiences God’s fullness. It is a satisfaction that can be characterized as a knowledge that one will never thirst again. While he knows in his humanity that he lacks much, that he has needs, that he can always improve, yet in His spirit he is filled, perfect, complete. It is the knowledge that our sins are perfectly and completely forgiven. It is the understanding that we possess the perfect righteousness of Christ, for that is how the Father now sees us. It is the awareness that “My God will supply all your needs according to his riches in glory in Christ Jesus.” It is the experience of being “filled with all the fulness of God.” And it is the confidence that “he who began a good work in you will bring it to completion at the day of Jesus Christ (Philippians 1:6).”
Without this, there will always be an emptiness, a thirst, a lack of satisfaction in the human soul. And if God has given you the grace to sense this lack, then all you need is to turn to him to receive the water that one can drink and never thirst again, for the water that he gives us is “a well of water springing up unto eternal life (John 4:14).”
