What has Jesus been doing since His resurrection?
After being raised from the dead, Jesus was called back to glory and seated at the Father's right hand. He remains there until His enemies are made His footstool. That 'until' marks the time when He will return to deal with Israel, His covenant people.
Les teaches that after Israel rejected the King and His kingdom and the King was crucified, God raised Him from the dead and called Him back to glory. There He sits at the Father's right hand until His enemies are made His footstool. That 'until' signifies the time when He will return once again to deal with His nation, His covenant people Israel. The context also notes that during the final seven years, after the age of grace has ended and the church is gone, 144,000 sealed Jews will proclaim the gospel of the kingdom, telling the world the King is coming.
