G. Vos: “Man belongs to two spheres. And Scripture not only teaches that these two spheres are distinct, it also teaches what estimate of relative importance ought to be placed upon them. Heaven is the primordial, earth the secondary creation. In heaven are the supreme realities; what surrounds us here below is a copy and shadow of the celestial things. Because the relation between the two spheres is positive, and not negative, not mutually repulsive, heavenly-mindedness can never give rise to neglect of the duties pertaining to the present life. It is the ordinance and will of God, that not apart from, but on the basis of, and in contact with, the earthly sphere man shall work out his heavenly destiny."
