John 5:42

But I know you
Being the omniscient God, he knew not only their persons, but their hearts, the thoughts of their hearts; what was in them, and what was wanting in them: particularly,

that ye have not the love of God in you;
and which is not in any man's heart naturally; for the carnal mind is enmity to God; and men, by nature, are haters of him, and enemies in their minds to him, till this grace, which is a fruit of the Spirit, is implanted in them, in regeneration: love to God, is one of the weightier matters of the law, the Jews passed over; without which, all the actions of men signify nothing: this they made great pretensions to, and would have had it thought, that it was from love to God, that they sought to kill Jesus, for his violation of the sabbath, and making himself equal with God; but it was not from a delight in the sabbath, or from love to the Lord of it, but out of ill will to Christ, that they expressed such dissembled piety and false zeal: they were lovers of themselves, and not God; they were covetous men, and loved the world, and the things in it, which is inconsistent with the love of the Father; and besides, if they had loved him, they would have loved him that was begotten of him, and not sought to have killed him.
