What was God the Father's invitation for the ascension?
The Father's invitation for the ascension was, "Sit at My right hand until I make Your enemies Your footstool," as stated in Psalm 110:1. This call to sit at the Father's right hand preceded the Son's ascension, and He accepted it.
Les explains that Psalm 110:1 records the Father's words to the Son: "Come sit at my right hand until I make your enemies my footstool." Les says that was the invitation for the ascension, and He did sit. According to the Old Testament, He would not have stayed long before returning to set up His kingdom—if Israel had obeyed and believed Jesus was the Christ. But Israel rejected in unbelief, so God turned to the Gentiles with the age of grace.
The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
