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. – 3
If this be the cavil, we reply in the affirmative that the Scripture is true; that Jesus did mean all, and even more than he said or deemed it safe to say at that time. His words are unmistakable, for they form propositions of self-evident demonstrable truth. Doctrines that deny the substance and practicality of all Christ’s teachings cannot be evangelical; and evangelical religion can be established on no other claim than the authenticity of the Gospels, which support unequivocally the proof that Christian Science, as defined and practised by Jesus, heals the sick, casts out error, and will destroy death.
