Matthew Poole and continuators on Acts 3:21

21 Whom the heaven must receive , until the times of restitution of all things , which God hath spoken by the mouth of all his holy prophets, since the world began.

That is, contain after it hath received him, as a real place doth a true body; for such Christs body was, which was received into Heaven: and Heaven is the Palace and Throne of this King of Kings, and Lord of Lords, where he shall reign until he hath put all his enemies under his feet, 1 Cor. 15.25.

Or restauration of all things, when all things shall be restored to that condition from which sin put them: for the fall hath maim'd and disordered the whole Universe; and probably, there is not that excellency in any of the Creatures, which there was at first, before man (for whom they were made) by his sin brought death to himself, and as it were a dead colour over all them; this makes the whole Creation groan and travail in pain until now, Rom. 8.22. But the end of the World will be a time of restitution of all things, unto man especially; who shall be then restored unto God, and to a blessed Immortality: for unless this be granted, all their Preaching and Prophesying was in vain, 1 Cor. 15.14.
