SEV Biblia, Chapter 8:18
YO SOY el que doy testimonio de mí mismo, y da testimonio de mí el que me envi, el Padre.
John Gill's Bible Commentary
Ver. 18. I am one that bear witness of myself , etc.] As he does of his sonship, in ( 1 John 5:7). And the Father that sent me, beareth witness of me ; as he did, by the descent of the Spirit upon him at his baptism, and by a voice from heaven, both at that time, and at his transfiguration, and by the miracles which he wrought; and particularly he bore testimony of him, long before, in prophecy, that he was the light of the world he now said he was, ( Isaiah 42:6); so that here were two testifiers, his Father and himself; which show them to be two distinct divine persons, and equal to each other: and now if the testimony of two men is true, firm, and authentic, and to be depended upon and received, then much more the testimony of two divine persons; (see 1 John 5:9).
Matthew Henry Commentary
Verses 17-20 - If we knew Christ better, we should know the Father better. Thos become vain in their imaginations concerning God, who will not learn of Christ. Those who know not his glory and grace, know not the Fathe that sent him. The time of our departure out of the world, depends upo God. Our enemies cannot hasten it any sooner, nor can our friends dela it any longer, than the time appointed of the Father. Every tru believer can look up and say with pleasure, My times are in thy hand and better there than in my own. To all God's purposes there is a time.
