Written by Dallas Willard (1935-2013), an American philosopher known for his writings on Christian spiritual formation. This is an excerpt from his book “Renovation of the Heart.”
We live from our heart. The part of us that drives and organizes our life is not the physical. This remains true even if we deny it. You have a spirit within you and it has been formed. It has taken on a specific character. I have a spirit and it has been formed. This is true of everyone. The human spirit is an inescapable, fundamental aspect of every human being; and it takes on whichever character it has from the experiences and the choices that we have lived through or made in our past. That is what it means for it to be “formed.” Our life and how we find the world now and in the future is, almost totally, a simple result of what we have become in the depths of our being—in our spirit, will, or heart. From there we see our world and interpret reality. From there we make our choices, break forth into action, try to change our world We live from our depths—most of which we do not understand.
Watch over your heart with all diligence, for from it flow the springs of life [Proverbs 4:23]
