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 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.
— John Piper
