John 5:17-19

17But Jesus answered them, My Father worketh until now, and I work. 18Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God. 19Then answered Jesus and said to them, Verily, verily, I say to you, The Son can do nothing by himself, but what he seeth the Father do: for whatever he doeth, these also doeth the Son likewise.
