The Christian religion is primarily about a transformation of consciousness. This takes spiritual practice and the cultivation of wisdom. In another time this was called cultivating the supernatural organism, what Paul called “a new creation.” So the main thing is to be transformed into God, what the early church called deification, theosis, divinization.

Transformation: Writings on Centering Prayer
