Charles Fillmore's last book is compiled from a series of articles written by him over many years. In it he approaches the spiritual realm from the viewpoint of science. He demystifies the holiness of our relationship to God and the universe and remystifies us by showing us Jesus' teachings as scientific theory: Christianity spiritual interpreted shows that Jesus understood the deeper things of God's universe. He understood exactly what the conditions were on the invisible side of life, which is termed in His teaching the 'kingdom of God' or the 'kingdom of the heavens.'
