Again the high priest asked him, “Are you the Christ, the Son of the Blessed?” And Jesus said, “I am, and you will see the Son of Man seated at the right hand of Power, and coming with the clouds of heaven.”
As Jesus stood before the high priest, brought their under illegal arrest at night and submitting to hostile questioning, He confirmed His unique role as Messiah by answering only one question put to Him. When asked if He was the Messiah, Jesus replied with a firm affirmation by stating in terms of deity: "I am". Then He went on to state that He would return as judge in power one day. Right then the high priest gazed on Jesus as his prisoner, but one day the roles would be reversed and the high priest would stand before Jesus as his judge to answer for what he had done.
Jesus made Himself vulnerable. We must remember that. He gave Himself over to be beaten, tried, and crucified. The gospels clearly show this. He knew it was coming. He gave Himself to the Father's will. And even at these awful moments, Jesus shows us that He is in control, knowing full well what His task would be and commiting to die and then to be raised to life. After that His power as Lord would always be worshiped and proclaimed.
This submission and humility is coming from the Lord of Heaven for our sakes so that redemption and forgiveness of sings might come to all who believe. The high priest looked like he had the upper hand in this exchange, but the Son of Man was clearly the one in charge here.
