And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book (Exodus 32:31-33).” Remember, according to Revelation 3:5, if you believe on the Lord Jesus Christ, he will not blot your name out. What is the sin that can cause your name to be blotted out? It is unbelief. It is the rejection of Jesus Christ as Saviour. This is the unpardonable sin. (See John 3:36, I John 5:12).
