Searching for and rediscovering the True Self is the fundamentum, the essential task that will gradually open us to receiving and giving love to God, others, and ourselves. Grace builds on nature; it does not avoid or destroy nature. You are created in the image of God from the very beginning (Genesis 1:26-27, Ephesians 1:3-4).
You (and every other created thing) begin with your unique divine DNA, an inner destiny as it were, an absolute core that knows the truth about you, a true believer tucked away in the cellar of your being, an imago Dei that begs to be allowed, to be fulfilled, and to show itself. "You were chosen in Christ before the world was made--to stand before God in love--marked out beforehand as fully adopted sons and daughters" (see Ephesians 1:4-5). This is your True Self. Historically, it was often called "the soul." - Fr. Richard Rohr
