Romans 14:10 (KJV)

“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.”

We judge our brother or sister, for their actions as a Christian, and in doing so, what we fail to do is to realize that we too, are going to stand in judgement, “The Judgment Seat of Christ.” The question at hand has to do with a brother or sister in Christ, and the Judgment at hand has to do with brothers and sisters in Christ, standing before the Lord, in judgment. Even a lost man knows in his heart about “judgment day.” But there are actually 7 different judgments listed in scripture, and there is a separate judgment for Christians, than there is for those who have rejected the Lord Jesus Christ’ finished work on the cross of calvary.
Here, in Chapter 14, we have the first mention of “The Judgment Seat of Christ.” The judgment that Paul is discussing here in this chapter, is the judgment, for believers, for the “works” that you do for the Lord, after salvation. The judgment for a lost man, is the “Great White Throne Judgment.” At “The Judgment for sin on Calvary,” Christ paid the penalty for your sin, by taking your sin upon Himself, and dying in your place, for your sin. The judgment and penalty for sin is death, and Christ was judged for your sin, and paid the penally for your sin, when He died in your place for your sin.  For that reason, at the Judgment Seat of Christ, because you placed your faith in Jesus Christ, you do not have to fear judgment of your sins because He took your judgment upon Himself for you, in your place.
1 Peter 2:24 (KJV)
“Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.”

So, if you are saved, you will stand before Christ, at the “Judgment Seat of Christ,” and you will be judged for the work you did for Christ AFTER salvation. This judgment, takes place after the rapture of the church. Every man’s work, for Christ, after salvation is going to be brought into judgment; or “made manifest.”
2 Corinthians 5:10 (KJV)
“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.”
The moment that you were saved, God called you into His labor force. He put you to work for Him, to represent Him here on earth, and you are going to be judged for the quality of the labor that you did, whether it was good work, or bad work. It won’t be for the quantity of work that you do for Him, but the quality.
