Every one of us is rewarded, or not, for the things we do in life; the same will be true when we get to heaven.  How we lived our lives as a Christian will be judged by Christ Jesus. This is known as the "Bema Judgment."  Of the Bema Judgment, the Bible says:

"For we must all appear before the judgment seat of Christ, that each one may receive what is due him for the things done while in the body, whether good or bad." 1

William McDonald, in his book Believer's Bible Commentary wrote:

"The judgment seat of Christ will reveal our lives of service for Christ exactly as they have been.  Not only the amount of our service, but also its quality, and even the very motives that prompted it will be brought into review.

Although sins after conversion will have an effect on our service, a believer's sins, as such, will not be brought into review for judgment at this solemn time.  That judgment took place over 1900 years ago, when the Lord Jesus bore our sins in His body on the tree.  He fully paid the debt that our sins deserved, and God will never bring those sins into judgment again (John 5:24.)  The judgment seat of Christ has to do with our service for the Lord.  It will not be a matter of whether we are saved or not; that is already an assured fact.  But it is a matter of reward and loss at that time."
