jesus also taught that one must be born again in order to receive god's spirit, otherwise one remains separated from god, acting merely from their own mind, thus being vulnerable to deception by human philosophies or the many spiritual philosophies which do not come from god but from fallen angels, which are within various false religions. after a person consciously accepts the free gift of eternal life, which jesus's sacrifice offers, god comes to live in the individual, as god lived in humankind before the fall.
