John 5:18 explains why some of the religious leaders in Jerusalem wanted to kill Jesus: he had healed on the Sabbath and, in doing so, spoke of God as his own Father, which they understood as claiming equality with God. The verse is a narrator’s comment, so it tells us what the Jewish leaders concluded about Jesus rather than giving his own words. The author is John, writing to readers who needed to know who Jesus was.
For this cause therefore the Jews sought all the more to kill him, because he not only broke the Sabbath, but also called God his own Father, making himself equal with God.

What John 5:18 Means
The phrase “for this cause therefore” points back to the previous verses, where Jesus healed a man at the pool of Bethesda on the Sabbath and told him to pick up his mat and walk. The leaders had already been upset about the Sabbath breach. Verse 18 says their hostility grew stronger, “all the more,” because Jesus went further in his reply: he called God his own Father.
Here the verse explains the logic the leaders drew. In their view, calling God “my Father” in this personal sense placed Jesus on a level with God himself. The verse does not say whether they were right. It records their conclusion and their decision to act on it, which is a reminder that the story of Jesus has always forced people to decide what they think about his identity.
What the verse does not promise is that the leaders correctly understood Jesus’ intent, or that every reader will agree with their reading. It shows the intensity of the conflict and the stakes of the claim, nothing more.
The Context of John 5:18
The Gospel of John is traditionally attributed to the apostle John, one of Jesus’ closest followers, and it was written to deepen faith in Jesus as the Son of God (John 20:31). Its audience was likely a Christian community that knew Jewish practices well and had experienced tension with the synagogue, which explains why “the Jews” appear as the chief opponents in this Gospel.
The verses just before and after set the scene. In verses 17 and 19 to 21, Jesus answers the charge by saying that his Father is still working on the Sabbath and that the Son does only what he sees the Father doing. Read with those lines, verse 18 is not a random accusation but the point at which Jesus’ answer makes the leaders see exactly what he is claiming about his relationship to the Father.
