For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned.
Romans 12:3
In choosing faith as the measure of the new self, Paul is choosing an absolutely unique act of the new mind. What is the essence of faith? Faith is looking away from ourselves to another. Faith is total dependence on another. When faith stands in front of a mirror, the mirror becomes a window with the glory of Christ on the other side. Faith looks to Christ and enjoys him as the sum and judge of all that is true and good and right and beautiful and valuable and satisfying.
So what Paul is saying is that the essence of the new Christian mind is that we see and savor—we behold and we embrace—Jesus Christ and not ourselves as the supreme truth and supreme treasure in the universe.
Do you see the astonishing thing that Paul is doing here? As he watches people puff themselves up, thinking of themselves too highly, he says, Here is how to think soberly about yourself: Make faith the measure of your mind. Make faith the measure of your heart, your life. And so he turns self-exaltation upside down. He says, Do you want to have significance? Then look to Christ as infinitely significant. Do you want to have value? Then look to Christ as infinitely valuable. Do you want to want to have esteem? Then look to Christ as worthy of infinite esteem.
Don’t make mistake here. I am not saying what so much contemporary Christian Popular Psychology says. I am not saying: Do you want to have significance? Then look to Christ as a means to your significance. I am not saying: Do you want to have value? Then look to Christ as the one who gives you value. I am not saying: Do you want to have esteem? Then look to Christ as the means of your esteem. I am not saying that in the renewed mind Christ is a means to the goal of your significance and esteem and value. I am saying: you were made to embrace him as infinitely significant and infinitely valuable and infinitely worthy of esteem. That is what the renewed mind does and loves to do. That is the deepest identity of the new mind.
I’ll say it again: Do you want to have significance? Then embrace Christ as the one who is infinitely significant to you. Do you want to have value? Then embrace Christ as infinitely valuable. Do you want to want to have esteem? Then embrace Christ as worthy of infinite esteem.
Our faith in Christ is the measure of our significance and value and esteem, because faith means looking away from ourselves to Christ and embracing him as the all-satisfying embodiment of all that is significant and valuable and worthy of esteem. The measure of our new self in Christ—the renewed mind—is the degree to which we look away from ourselves to Christ as our truth and treasure.
If Christ is more to you, you are more. If Christ is less to you, you are less. Your measure rises and falls with your measure of him. Your valuing him is the value that you have. Your esteeming him is the esteem that you have. Your treasuring him is the treasure that you are.
