John 5:17-19 NIV

[17] In his defense Jesus said to them, “My Father is always at his work to this very day, and I too am working.” [18] For this reason they tried all the more to kill him; not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God. [19] Jesus gave them this answer: “Very truly I tell you, the Son can do nothing by himself; he can do only what he sees his Father doing, because whatever the Father does the Son also does.
