Lewis describes what he calls "the Christ-life" within us and how we enter fully into that life. "The Christian...  thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it."
