John 5:17

My Father - God.

Worketh hitherto - Worketh “until now,” or until this time. God has not ceased to work on the Sabbath. He makes the sun to rise; He rolls the stars; He causes the grass, the tree, the flower to grow. He has not suspended His operations on the Sabbath, and the obligation to “rest” on the Sabbath does not extend to Him. He created the world in six days, and ceased the work of creation; but He has not ceased to govern it, and to carry forward, by His providence, His great plans on the Sabbath.

And I work - “As God does good on that day; as he is not bound by the law which requires his creatures to rest on that day, so “I” do the same. The law on that subject may be dispensed with, also, in my case, for the Son of man is Lord of the Sabbath.” In this reply it is implied that he was equal with God from two circumstances:

1. Because he called God his Father, John 5:18.
2. Because he claimed the same exemption from law which God did, asserting that the law of the Sabbath did not bind him or his Father, thus showing that he had a right to impose and repeal laws in the same manner as God. He that has a right to do this must be God.
