Every man must read the Word (Jesus) for himself. One may read it in one shape, another and another: all will be right if it be indeed the Word they read, and they read it by the lamp of obedience. He who is willing to do the will of the Father shall know the truth of the teaching of Jesus. The spirit is ‘given to them that obey him.’
To him who obeys, and thus opens the door of his heart, God gives the Spirit of His Son, the Spirit of Himself, to be in him and lead him to the understanding of all truth; the true disciple shall thus always know what he ought to do, though not necessarily what another ought to do. The spirit enlightens by teaching righteousness. No teacher should strive to make men think as he thinks, but to lead them to the living Truth, the Master Himself, who will make them in themselves know what is true by the very seeing of it. To be the disciple of Christ is the end of being; to persuade men to be his disciples is the end of teaching.
