In this fourth video, Kirby de Lanerolle continues to explain immortality. He starts by talking about being born in the image of God vs. being matured in our understanding. Adam was born in the image of God without an understanding of good and evil. We are made mature through righteousness in the spiritual realm. Our spirit or souls have already been made perfect through what Christ has done, but our bodies have not. Kirby shows how the spiritual realm affects our world around us and so much more.
