1) "For we must all appear," (tous gar pantas hemas phanerothenai dei) "For (it) is necessary that all of us be manifested," are to appear, for review, for accounting; This appearance of the redeemed is to determine rewards and losses of rewards, not salvation, which is eternal, 1 Corinthians 3:14-15, Mark 4:22; Romans 2:16.
2) "Before the judgment seat of Christ," (emprosthen tou Bematos tou Christou) "Before the tribunal (judgment place) of Christ;" to be judged, not to determine salvation, but the loss or gain of rewards, based upon one’s life’s conduct morally, ethically, and’ spiritually, after salvation, 2 John 1:8; Revelation 22:11-12; Revelation 22:15; John 5:22.
THE JUDGMENT SEAT OF CHRIST
The image of Christ on the judgment seat is the same as that in Romans 16:10 (where, however, in the best MSS, it is "the seat of God"); and the expression is peculiar to these two passages, being taken from the tribunal of the Roman magistrate, as the most august representation of justice which the world then exhibited. "The Bema" was a lofty seat raised on an elevated platform, usually at the end of the Basilica, so that the figure of the judge must have been seen towering above the crowd which thronged the long nave of the building. So sacred and solemn did this seat and platform appear in the eyes, not only of the heathen, but of the Christian society of the Roman Empire, that when, two centuries later, the Basilica became the model of the Christian place of worship, the name of Bema (or tribunal) was transferred to the chair of the Bishop; and this chair occupied in the apse the place of the judgment seat of the praetor. In classical Greek the word Bema was applied not to the judgment seat, which did not exist in Grecian states, but to the stone pulpit of the orator. In the N.T. (with the exception of Acts 12:5) it is always used for a "judgment seat." The more unusual figure for the judgment is a "throne". Comp. Ma. 25:31, "He shall sit on the throne of His glory;" Revelation 20:11, "a great white throne;" Daniel 12:9, "His throne was like a fiery flame."
