It can readily be deduced from this text that Jesus Christ is a divine self. He is the one who rewards people according to their deeds, whether they be good or bad. He is our Judge. We are accountable to God because He is our Creator.
Furthermore, Christ's right and authority to judge us is rooted in His omniscience. He is divine in the same sense as the Father and Holy Spirit are divine. He is God incarnate. The Lord has fully comprehensive knowledge of everything.
Jesus Christ searches the hearts and minds of people. He knows everything about us all. There is not a thing hidden from His sight or unknown to Him.
