But ye seek to kill me, a man that hath told you the truth. Ye shall know the truth, and the truth shall make you free. God is a spirit, and they that worship him must worship him in spirit and in truth. Keep my sayings, and ye shall know of my sayings whether they be true.” No proofs of this doctrine were offered except its truth, the correspondence of the doctrine with the truth.

The whole teaching consisted in the recognition of truth and following it, in a greater and greater attainment of truth, and a closer and closer following of it in the acts of life. There are no acts in this doctrine which could justify a man and make him saved. There is only the image of truth to guide-him, for inward perfection in the person of Christ, and for outward perfection in the establishment of the kingdom of God.
