C.S. Lewis on Eternal Progression

The Gods who dwell in heaven . . . were once in a fallen state . . . they were exalted also, from fallen men to celestial Gods.

. . . from Him there began the union of the divine with the human nature. This was so that the human – by communion with the divine – might rise to be divine. This not only happened in Jesus, but also in all those who not only believe, but enter upon the life that Jesus taught.

If there was a point where man in his progression could not proceed any further, the very idea would throw a gloom over every intelligent and reflecting mind. God himself is increasing and progressing in knowledge, power, and dominion, and will do so, worlds without end. It is just so with us.

If anyone swear by Tash and keep their oath for the oath’s sake, it is by me that they have truly sworn, though they know it not, and it is I who reward them. And if anyone do a cruelty in my name, then, though they say the name Aslan, it is Tash whom they serve and by Tash their deed is accepted.

Now the whole offer which Christianity makes is this: that we can, if we let God have His way, come to share in the life of Christ. If we do, we shall then be sharing a life which was begotten, not made, which always existed and always will exist. Christ is the Son of God. If we share in this kind of life we also shall be sons of God. We shall love the Father as He does and the Holy Ghost will arise in us. He came to this world and became a man in order to spread to other men the kind of life He has ⁠— by what I call “good infection.” Every Christian is to become a little Christ. The whole purpose of becoming a Christian is simply nothing else.
