Nathan showed concern for King David s soul. Paul withstood Peter to his face when Peter separated from the Gentiles when Jews entered the room. Not only did Peter sin but he caused others to sin also. This shows the importance of exposing error and restoring the lost Christian before the influence of the erring one corrupts others. These are just three biblical examples of someone telling another of sin in his life.
Angels are concerned for lost souls.
If we love God, we are commanded to keep all his commands. Included in this is to restore those who have fallen away into sin. Verse two continues with the thought encouraging the Galatians to bear one another s burdens to help and encourage them overcome their sins. Sometimes we allow our fear of rejection or the fear of physical or mental harm to keep us from telling someone they are sinning. Paul s love for God and his desire to obey all God s commands gave him the courage to tell Christians they were living in sin.
