"For this reason, Christ died and returned to life so that he might be the Lord of both the dead and of the living. You, then, why do you judge your brother? Or why do you judge your brother? For we all stand before God's judgment seat. It is written:
'As surely as I live,' says the Lord
'every knee will bow before me;
every tongue confess to God.'
So then, each of us will give an account of himself to God."
So what have you done with the life given to you by God? Will you be able to tell God of all the wonderful things your life and love has accomplished, or are there things in your life that you are ashamed of? All things will be brought into the light.
God is judge over all because of his resurrection. He died in order to be rendered as just and in so being the one who justifies sinners (which we all are). The rain falls on both righteous and wicked alike. As surely as Christ lives (and we know He lives for He is risen!), every tongue will give a testimony before God. The only good testimony, the only good righteous defense, and the only hope we have, comes through faith in Jesus Christ. Jesus pleads our case when we stand in judgment before the throne. He pleads with his blood and is victorious because He is also the judge. Only he can raise the dead to life.
