Again he thus disputeth, that every agent which can work, and doth not work, if it afterward work, it is either thereto moved by itself, or by somewhat else: and so it passeth from power to act.

But God (saith he) is immovable, and is neither moved by himself, nor by any other: but being always the same, doth always work.

Whence he concludeth, if the world were caused by God, that he was forever the cause thereof: and therefore eternal.

The answer to this is very easy, for that God's performing in due time that which he ever determined at length to perform, doth not argue any alteration or change, but rather constancy in him.

For the same action of his will, which made the world forever, did also withhold the effect to the time ordained.
