The psalmist David said, "Thy righteousness is an everlasting righteousness, and Thy law is the truth."
From these passages we learn that when Christ said, "When He, the Spirit of truth, is come, He will guide you into all truth,"
He meant that the Spirit would lead them into a proper understanding of that which had already been revealed.
He plainly stated this when He said, "He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."
*Many things that Christ said were not understood at the time; but they were made plain by the Spirit, after Christ had ascended to heaven.
*And it is thus that the Spirit teaches us now; it leads those who are humble and teachable into a proper understanding of the written Word of God."
