John Calvin Commentary John 5:42

"But I know you, that ye have not the love of God in yourselves." — John 5:42 (ASV)

That you have not the love of God in you. The love of God here represents all religious feelings; for no one can love God without contemplating Him with admiration and submitting entirely to His authority. On the other hand, when the love of God does not prevail, there can be no desire to obey Him. This is why Moses gives this as the summary or recapitulation (ἀνακεφαλαίωσις) of the Law:

thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy might,
(Deuteronomy 6:5).
