A.W. Tozer once wrote, "The healthy soul, like the healthy bloodstream has its proper proportion of white and red cells. The red carry the true faith, and the white cells are like disbelief--they pounce upon the dead and toxic matter and carry it out to the drain. Along with our faith in God must go a healthy disbelief in everything occult and esoteric. Numerology, astrology, spiritism and everything else that passes nowadays for religion must be rejected. These have no part in the life of the true Christian!"
