16 So the Jewish leaders began harassing Jesus for breaking the Sabbath rules.
17 But Jesus replied, "My Father is always working, and so am I." 18 So the Jewish leaders tried all the harder to find a way to kill him. For he not only broke the Sabbath, he called God his Father, thereby making himself equal with God.
19 So Jesus explained, "I tell you the truth, the Son can do nothing by himself. He does only what he sees the Father doing. Whatever the Father does, the Son also does.

Commentary on John 5:10-16
(Read John 5:10-16)
Those eased of the punishment of sin, are in danger of returning to sin, when the terror and restraint are over, unless Divine grace dries up the fountain. The misery believers are made whole from, warns us to sin no more, having felt the smart of sin. This is the voice of every providence, Go, and sin no more. Christ saw it necessary to give this caution; for it is common for people, when sick, to promise much; when newly recovered, to perform only something; but after awhile to forget all. Christ spoke of the wrath to come, which is beyond compare worse than the many hours, nay, weeks and years of pain, some wicked men have to suffer in consequence of their unlawful indulgences. And if such afflictions are severe, how dreadful will be the everlasting punishment of the wicked!
Commentary on John 5:17-23
(Read John 5:17-23)
The Divine power of the miracle proved Jesus to be the Son of God, and he declared that he worked with, and like unto his Father, as he saw good. These ancient enemies of Christ understood him, and became more violent, charging him not only with sabbath-breaking, but blasphemy, in calling God his own Father, and making himself equal with God. But all things now, and at the final judgment, are committed to the Son, purposely that all men might honour the Son, as they honour the Father; and every one who does not thus honour the Son, whatever he may think or pretend, does not honour the Father who sent him.
