When a person acquires saving faith and receives Jesus, they are reborn, and the Holy Spirit lives within them. How then can a person’s saving faith disintegrate to the point where they want to merge Christ with pagan beliefs?
This growth is a moral and spiritual transformation “from one degree of glory to another.” We are being progressively restored to greater and greater possession of the image of God which was corrupted at the fall of Adam.
Just like a baby, we have to explore, taste, learn, feel, sing, worship, dialog with God, and fellowship with other Christians. We need all of these and more, so we grow up to be a healthy child of God.
As Christians, we rightly focus on Jesus as our Redeemer. However, the victory Jesus won through His birth, sinless life, death, burial, and resurrection is even more significant than just the salvation available to us through Him.
