John 5:42 says that Jesus knew the hearts of the people he was speaking to, and that their hearts lacked the love of God. The verse is a diagnosis, not a curse: Jesus is pointing out that outward religious activity can exist without an inward relationship with God. Jesus speaks these words to the Jewish religious leaders in Jerusalem, right after he heals a man at the Pool of Bethesda and is challenged for doing it on the Sabbath.
But I know you, that you don’t have God’s love in yourselves.

What John 5:42 Means
The phrase “I know you” carries more weight than it first appears. In Scripture, to know someone means to be deeply acquainted with their character, not merely to recognize their face. Jesus is saying he sees past the leaders’ public piety to what is really going on in them.
The phrase “God’s love in yourselves” describes where the love of God is meant to dwell. Jesus does not say these men lack knowledge about God or lack religious practice. They search the Scriptures diligently, as verse 39 notes. His complaint is that the love of God has not taken root in their own hearts, so their study has not produced the life it was meant to produce.
The verse does not say that God has rejected these men or that they cannot change. Its purpose is to expose the gap between knowing about God and loving God, and the verses that follow show Jesus inviting them to come to him so they may have life.
The Context of John 5:42
John’s Gospel was written to show that Jesus is the Son of God and that believing in him brings eternal life (John 20:31). The author is traditionally identified as the apostle John, and the original audience was likely a community of early Christians who were learning to distinguish their faith from the synagogue. The debate in chapter 5 reflects that tension: Jesus is making claims about himself that the religious establishment rejects.
Just before verse 42, Jesus tells his listeners that the Scriptures testify about him, yet they refuse to come to him for life. Verse 42 explains the reason for that refusal. Right after it, Jesus says he has come in his Father’s name and they do not receive him, and he asks how they can believe when they seek glory from one another rather than from God. Read this way, verse 42 is the hinge of the argument: the problem is not a lack of evidence but a heart that has not been opened to the love of God.

A Short Prayer From John 5:42
Lord, you know me completely, including the places where my heart has grown cold while my habits have stayed the same. I do not want to rely on knowing about you without truly loving you. Search me, and pour your love into the places that feel empty or proud. Turn my eyes away from the approval of others and toward your glory alone. Teach me to receive your love and let it shape how I treat the people around me. Amen.
