No one has ascended into heaven, but he who descended out of heaven, the Son of Man, who is in heaven.
[1.] That the truths Christ taught were very certain and what we may venture upon (John 3:11): We speak that we do know. We; whom does he mean besides himself? Some understand it of those that bore witness to him and with him on earth, the prophets and John Baptist; they spoke what they knew, and had seen, and were themselves abundantly satisfied in: divine revelation carries its own proof along with it. Others of those that bore witness from heaven, the Father and the Holy Ghost; the Father was with him, the Spirit of the Lord was upon him; therefore he speaks in the plural number, as John 14:23: We will come unto him. Observe, First, That the truths of Christ are of undoubted certainty. We have all the reason in the world to be assured that the sayings of Christ are faithful sayings, and such as we may venture our souls upon; for he is not only a credible witness, who would not go about to deceive us, but a competent witness, who could not himself be deceived: We testify that we have seen. He spoke not upon hear-say, but upon the clearest evidence, and therefore with the greatest assurance. What he spoke of God, of the invisible world, of heaven and hell, of the divine will concerning us, and the counsels of peace, was what he knew, and had seen, for he was by him as one brought up with him, Proverbs 8:30. Whatever Christ spoke, he spoke of his own knowledge. Secondly, That the unbelief of sinners is greatly aggravated by the infallible certainty of the truths of Christ. The things are thus sure, thus clear; and yet you receive not our witness. Multitudes to be unbelievers of that which yet (so cogent are the motives of credibility) they cannot disbelieve!
