And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. John 17:3.
The Lord Jesus said to His disciples when He was with them, “I have yet many things to say unto you, but ye cannot bear them now.” He could have made disclosures which would have absorbed the attention of the disciples and caused them to lose sight of His former instruction that He wished to be the subject of their most earnest thought. But He withheld those things that they would have been amazed to hear, and that would have afforded them opportunity to cavil, to create misunderstanding and disaffection. He would give no occasion for persons of little faith and piety to mystify and misrepresent the truth, and thus create factions.
Jesus could have presented mysteries that would have given subject for thought and investigation for generations, even to the close of time. Himself the source of all true science, He could have led people to the investigation of mysteries, and age after age their minds would have been so thoroughly absorbed that they would have felt no desire to eat the flesh and drink the blood of the Son of God.
Jesus well knew that Satan is constantly working to excite curiosity, and to busy people with conjecture. Thus he seeks to eclipse the grand and momentous truth that Christ wished to be ever prominent before their minds. “For this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.”
There is a lesson for us in those words of Christ spoken after the feeding of the five thousand. He said, “Gather up the fragments that remain, that nothing be lost.” These words meant more than that the disciples should gather the broken pieces of bread into baskets. Jesus meant that they should mark His words, should study the Scriptures, and treasure every ray of light. Instead of searching for a knowledge of something that God had not revealed, they were carefully to gather up what He had given them.
Satan had tried to eclipse from human minds the knowledge of God, and to eradicate from their hearts the attributes of God.... That which God had revealed was misconstrued, misapplied, and mingled with satanic delusions. Satan will quote Scripture in order to deceive. He tried to deceive Christ in this way. So he still tries to deceive.... Christ came to adjust truths that had been misplaced and made to serve the cause of error. He recalled them, repeated them, ... and bade them stand fast forever.—Manuscript 32, 1896 (Manuscript Releases 17:20, 21).
