He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. — John xiv. 12. – 6
The condition insisted upon is, first, “belief;” the Hebrew of which implies understanding. How many to-day believe that the power of God equals even the power of a drug to heal the sick! Divine Science reveals the Principle of this power, and the rule whereby sin, sickness, disease, and death are destroyed; and God is this Principle. Let us, then, seek this Science; that we may know Him better, and love Him more. (Eddy, Mary Baker, Miscellaneous Writings, p.193:31-6)
