A Restitution of All Things

Read this passage and put aside everything you know and then ponder what it means.

Acts 3

19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;

20 And he shall send Jesus Christ, which before was preached unto you:

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.
