Romans 14:10-12 — But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
For it is written, As I live, saith the Lord, every knee shall bow to Me, and every tongue shall confess to God.
So then every one of us shall give account of himself to God.
why dost thou judge — addressed to weak brother
why dost thou set a nought — addressed to stronger brother
judgment seat (Bema) = a platform
2 Corinthians 5:10 — For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.
1 Corinthians 3:9-15 — For we are labourers together with God: ye are God's husbandry, ye are God's building. According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon. For other foundation can no man lay than that is laid, which is Jesus Christ. Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. If any man's work abide which he hath built thereupon, he shall receive a reward. If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
We will account for ourselves, not for others.
