The books will be opened. The universe is witness in a spiritual sense to everything that happens, our thoughts, words, deeds. It also gets recorded in the heavenly books by the heavenly beings. Jesus wrote with his finger on the ground as he was asked to condemn someone to stoning, just before he turned to the crowd and asked the one without sin to cast the first stone. He knows all our sins are written. He is master over the writing of them, since as Son of Man it is he who will finally judge. We can be sure he knows our sinful deeds. He knows how they are written. He presides over the judgment of them. He can even forgive those deeds if he wishes. He has authority to know them, to have them written, to forgive them, and to refuse to condemn us if he chooses. One day the books will be opened. He will be there in charge. The Son of Man who knows what life as a true human is really like to live, yet he did not sin. His death on the cross was for your sins (and mine) to allow God to turn aside His wrath from those Jesus covers, and to allow our reconciliation with this Father, God who sent him, who raised him from the dead triumphant over death and temptation to sin. He, Jesus, the Son of Man, will judge each and every person and angels too. Alive from the dead, raised by God, alive forever, God has made him both Lord and Christ.
