John 5:16 - 5:18
16 And for this reason the Jews were persecuting Jesus, because He was doing these things on the Sabbath. 17 But He answered them, “My Father is working until now, and I Myself am working.” Jesus’ Equality with the Father
18 For this reason therefore the Jews were seeking all the more to kill Him, because He not only was breaking the Sabbath, but also was calling God His own Father, making Himself equal with God.
