Dallas Willard Daily Devotional, Day 1: Transformation of the Mind
The ultimate freedom we have as human beings is the power to select what we will allow our minds to dwell upon. It is in our thoughts that the first movements toward the renovation of the heart occur. Thoughts are the place where we can and must begin to change. There the light of God first begins to move upon us through the word of Christ, and there the divine Spirit begins to direct our will to God and his way. We are not totally free in this respect, but we do have great freedom here. We still have the ability and responsibility to try to retain God in our knowledge. And those who do so will surely make progress toward him; for if we truly do seek God as best we can, he, who always knows what is really in our hearts, will certainly make himself known to us.
Clearly our thoughts are one of the most basic sources of our life. By “thoughts” we mean all of the ways in which we are conscious of things—and it includes our memories, perceptions, and beliefs. Thoughts determine the orientation of everything we do and evoke the feelings that frame our world and motivate our actions. Interestingly, you can’t evoke thoughts by feeling a certain way. However, we can evoke—and to some degree control—our feelings by directing our thoughts.
Our essential nature as active and creative beings depends upon our ability to envision what is not the case, as well as what is. Our ability to plan for the future must constantly run ahead of reality. And this we do in thought. A will that runs ahead depends, of course, upon our ability to think; and what we think, imagine, believe, or guess sets boundaries to what we can or will choose, and therefore to what we can create.
As our senses present a landscape for our body and its actions, so our thoughts present the "lifescape"for our will and our life as a whole. Within that "thought lifescape," which includes our perceptions, we make the decisions that determine what we will do and who we will become.
