Adam Clarke on John 5:17

My Father worked hitherto, and I work - Or, As my Father worketh until now, etc., καθως being understood. God created the world in six days: on the seventh he rested from all creating acts, and set it apart to be an everlasting memorial of his work. But, though he rested from creating, he never ceased from preserving and governing that which he had formed: in this respect he can keep no sabbaths; for nothing can continue to exist, or answer the end proposed by the Divine wisdom and goodness, without the continual energy of God. So I work - I am constantly employed in the same way, governing and supporting all things, comforting the wretched, and saving the lost; and to me, in this respect, there is no sabbath.
