Commentaries:
It takes years for a reputation to be built up, but seemingly only a few minutes to destroy it. There are ample warnings in Scripture that if we appropriate God's Family name, and then by our behavior show our contempt for it, our names will be blotted out of the Book of Life (Exodus 32:33). Proverbs 10:7 teaches, "The memory of the righteous is blessed, but the name of the wicked will rot." Conversely, "He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before My Father and before His angels" (Revelation 3:5).
