Think of the soul as the computer system that runs the whole thing. And then the spirit is the executive center. It's the faculty of choice. And then you want that faculty governed by the truth of God and the Spirit of God.
Dallas WillardEveryone receives spiritual formation, just as everyone gets an education. The only question is whether it is a good one or a bad one. We need to take a conscious, intentional hand in the developmental process. We need to understand what the formation of the human spirit is, and how it can best be done as Christ would have it done. This is an indispensable aspect of developing a psychology that is adequate to human life.
Dallas WillardWhat we think is, in the adult person, very much a matter of what we allow ourselves to think, and what we feel is very much a matter of what we allow ourselves to feel. Moreover, what we think is very much a matter of what we wish and seek to think, and what we feel is very much a matter of what we wish and seek to feel. In short, the condition of our mind is very much a matter of the direction in which our will is set.
