"... that which is born of the Spirit is spirit" (John 3:6).
What is regeneration? It is the implanting of a principle of new spiritual life and a radical change in the governing disposition of the soul. The important thing to grasp is the whole idea of disposition. In addition to the faculties of our souls, there is something at the back of them that governs them all, and that is what we refer to as our disposition. Take two men. They have the same faculties, but one lives a good life, one lives a bad life. What makes the difference? The answer is that the good man has a good disposition, and this good disposition, this thing that is behind the faculties and governs them and uses them, urges him to use his faculties in the direction of goodness. The other man has an evil disposition; so he urges the same faculties in an entirely different direction. That is what one means by disposition.
When you come to think of it, and when you analyze yourself, your life and your whole conduct and behavior and that of other people, you will see at once that these dispositions are, of course, of tremendous importance. They are the condition, if you like, that determines what we do and what we are.
There is in every person a disposition that seems to determine the kind of person he or she is. It is this that directs the faculties and the abilities so that one person is artistic and the other scientific and so on. I am making this point to show that what happens in regeneration is that God so operates upon us in the Holy Spirit that this fundamental disposition of ours is changed. He puts a holy principle, a seed of new spiritual life, into this disposition that determines what I am and how I behave and how I use and employ my faculties.
A Thought to Ponder: Regeneration is a radical change in the governing disposition of the soul.
