Romans 14:9-12

For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living. 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.

Each one of us will have to stand for our own judgment. We should not worry about other and their actions, but instead worry about our own. We must strive to live our lives without sin so that way on our judgment day we will be able to give a good report.
