This is the final podcast in our three-part series on C S Lewis’ Mere Christianity. It covers the last Section of the book, Book IV, which focuses on the Christian doctrine of the Trinity and how it relates to salvation. Jack has no problem getting into theology. While he agrees that the experience of God is our primary goal, he points out that theological doctrines (like the Trinity) can function as maps or guides to this goal.
Salvation can be thought of in two ways. First, as a change in status whereby we go from being sinners and guilty before God to being forgiven and guilt-free. Second, as a process whereby our self-centered nature is replaced by God’s nature, that is, we are made fit creatures for Heaven. Jack emphasizes this second approach in this part of Mere Christianity, although he would most certainly agree that the other approach is also true. He discusses the nature of a super-personal God, a God that remains one and yet contains three personalities, and how we can actually participate in the life of this God, if we will it. Lewis also points out that this does really costs us ourselves as we currently are but results in our real selves as God intended us to be.
Jack also adds a helpful chapter on God’s relationship to time. (Essentially, how we get into difficulties by thinking of God as inside time as we are). However, we did not have time to cover it in this podcast
