But I know you, that you have not the love of God in you.
All Commentaries on John 5:42 Go To John 5
Cornelius a Lapide
AD 1637
But I know you, &c. "I know and penetrate the inmost recesses of your hearts (for I, being God, am the Searcher of hearts), and I see in them nothing of Divine love, but that they are full of ambition, avarice, and pride. And this is the reason why ye will not receive those clear testimonies which I bring forward in My favour. The root from whence your unbelief and obstinacy spring is not ambition of glory in Me, but your own lack of charity. For if ye truly loved God, ye would indeed acknowledge that I have been sent by Him, and am clearly described in the Scriptures." Thus even now the cause of heresy in many is a vitiated love, because indeed many love the liberty of the flesh which heresy teaches, and do not love God, who forbids it.
Cyril connects this verse with what precedes, thus,—"I have not proclaimed these great things about Myself for the sake of glory, that I may gain human praise, but that ye may learn (as I know) that the love of God is not in you, deprived of which, how can ye come to Me who am the Son of God?"
Differently also Maldonatus and Toletus: "I preach that I am Messiah, and the Son of God, not because I seek the vain glory of men, but because I know that ye have not that love of God which leads to eternal life, so that I may lead you to this love by faith, by which ye may believe in Me."
