What is included in the restitution of all things?

Les teaches that Acts 3:21 says heaven must receive Jesus until the times of restitution of all things, which God spoke by all His holy prophets since the world began. He emphasizes 'until' as a time word. Before the king and kingdom could come, Israel especially had to go through those seven horrible years of restitution. That restitution includes the lifting of the curse, the tribulation, the defeat of Satan, and the earth being regenerated and made gloriously beautiful again for the kingdom reign. Peter agreed with the Old Testament that Jesus had gone back to the Father's right hand. Psalms 110:1 says to sit at His right hand until His enemies are made His footstool, which would be done during the tribulation. Then Israel could have her king and kingdom, and Peter was expecting it. Les also notes Peter may have forgotten that Jesus had indicated Peter would suffer a very ignominious death, being enraptured with the idea that if Israel repented and believed, the Messiah would return and they could yet have the kingdom.
