Luke 22:69 says, “Hereafter shall the Son of man sit on the right hand of the power of God.” Did this happen when He was taken by the Sanhedrin at that moment or did He mean when He died on the cross, He would be at the right hand of God?”
As we shall see, Jesus would take His place “on the right hand of God” AFTER He died on the cross and rose again. God the Father would give Him that place of honor and glory for laying down His life on the cross in obedience to Him (see John 10:17-18 with Philippians 2:5-9; Acts 2:33a; 5:31).
In Psalm 110:1 King David foretold Christ being exalted to God’s right hand: “The LORD said to my Lord, ‘Sit at My right hand, till I make Your enemies Your footstool.” After His glorious resurrection this was fulfilled, as we read in Ephesians 1:20, “which He worked in Christ when He raised Him from the dead and SEATED HIM AT HIS RIGHT HAND in heavenly places.” We read elsewhere that Christ seated Himself at God’s right hand. Hebrews 1:3 declares, “when He had by Himself purged our sins, SAT DOWN AT THE RIGHT HAND OF THE MAJESTY ON HIGH.” Later, in Hebrews 10:12 we see this same truth: “But this Man, after He had offered one sacrifice for sins forever, SAT DOWN AT THE RIGHT HAND OF GOD.” And finally, in Hebrews 12:2, we read “Looking unto Jesus, who for the joy that was set before Him endured the cross, despising the shame, and has SAT DOWN AT THE RIGHT HAND OF THE THRONE OF GOD.”
All the verses quoted thus far give us a clear answer to your question, but I would like to draw your attention to another verse which adds another thought to this subject. In Matthew chapter 26 we have the same scene before us with the religious leaders (the chief priests, the scribes, and members of the Sanhedrin) challenging Jesus, hoping to have a reason to condemn Him to death by crucifixion. In both Luke and Matthew, they asked Him if He was “the Christ, the Son of God,” but in Matthew He added something. In verse 64 He said to them, “It is as you said. Nevertheless, I say to you, hereafter YOU WILL SEE the Son of Man sitting at the right hand of the Power, COMING ON THE CLOUDS OF HEAVEN.” He never mentioned them “SEEING Him coming on the clouds of heaven” in Luke 22:69: He simply mentioned that He “WOULD be sitting on the right hand of the power of God,” which is what we saw in the verses I referred to earlier. This begs the question, “When will they SEE HIM coming on the clouds of heaven?” We have the answer back in Matthew 24:29-30, “Immediately AFTER THE TRIBULATION of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of heaven will be shaken. Then the sign of the Son of Man will appear in heaven, and THEN all the tribes of the earth will mourn, and THEY WILL SEE THE SON OF MAN ON THE RIGHT HAND AND COMING ON THE CLOUDS OF HEAVEN WITH POWER AND GREAT GLORY.” The Jews who were rejecting Him when He was here on earth and wanting to put Him to death, are representatives of the Jews (the “tribes of the earth”) who will be alive when Christ comes to earth in power and glory. They will witness His “leaving the Father’s right hand in heaven” and then He will “sit on the throne of His glory” (Matthew 25:31). We had quoted Psalm 110:1 which spoke of Him sitting at God’s right hand (where He has been for 2,000 years!) but it went on to say “till I make Your enemies Your footstool.” When He leaves God’s throne to come to earth, He will subdue all His enemies! They will not only SEE HIM, but we read in Philippians 2:10-11 “that at the name of Jesus every KNEE shall bow, of those in heaven, and of those on earth, and of those under the earth, and that every TONGUE should confess that Jesus Christ is Lord, to the glory of God the Father.” They will indeed be subject to Him in that glorious day, not as those who are redeemed, but as those who are “under the earth” (in “hell”).
