Instructions to both weak and strong
For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. 10 You, then, why do you judge your brother or sister? Or why do you treat them with contempt? For we will all stand before God's judgment seat.
11 It is written: "'As surely as I live,' says the Lord, 'every knee will bow before me; every tongue will acknowledge God.'" 12 So then, each of us will give an account of ourselves to God.
The universality of death particularly suggests to the apostle yet another commonality between us and our fellow Christians. We will all individually have to give an account of ourselves to our just and holy God. In view of the great day of our own reckoning, how foolish it is to get all worked up about judging our brother!
Reinforcing that sobering thought with words from Isaiah, Paul writes, “For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. You, then, why do you judge your brother? Or why do you look down on your brother? For we will 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 will confess to God.”’ So then, each of us will give an account of himself to God.”
