Will believers have to answer for some of their sins at the judgment seat of Christ?

Les teaches that the idea believers will come before the judgment seat of Christ and have to answer for some of their sin is a mistaken report. He says, "Never, never," because our sins are forgiven, under the blood, and Christ took care of it. Believers will never stand before Him with sin on their back. When people in trying times wonder if an awful unconfessed sin is the cause, he asks if they are a child of God and tells them to forget the idea of having sin on their back; it is gone. He illustrates with an old preacher's phrase that sins are buried in the deepest sea with a sign over it, "No fishing." God has buried them in the deepest sea and removed them as far as east from west; they will not come back and plague us. This is being justified freely by His grace through redemption.
