That passage (often quoted by the replacement theology crew as some kind of proof) I have already debunked.
And yes, it is another passage far too difficult and nuanced for the hacks and duffers who profess but do not understand.
BOTH of Peters speeches (Acts 2 and 3) undoubtedly convey (and are MEANT to convey) the certain return of the kingdom to Israel.
Act 1:6
When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
Act 3:21
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.
You teach the doctrine of the pharisees that carnalizes everything spiritual because they are not of faith, but of the world.
