31 Then Moses returned to the Lord and said, “Oh, these people have committed a great sin, and have made for themselves a god of gold! 32 Yet now, if You will forgive their sin—but if not, I pray, blot me out of Your book which You have written.” 33 And the Lord said to Moses, “Whoever has sinned against Me, I will blot him out of My book.” (Exodus 32:31–33, NKJV)
God has a book. This means that God knows the names of those who are faithful to Him and obtain eternal life, and He knows those who commit sin against Him and lose their souls. “And anyone not found written in the Book of Life was cast into the lake of fire” (Rev. 20:15). Some say once a person is saved, that person can never be lost. This is false doctrine. God had saved Israel from Egyptian bondage, and now, because of their sin with the golden calf, they were in danger of being blotted out of God’s book. It was about Israel (His own people) that God said, “Whoever has sinned against Me, I will blot him out of My book.” Dear Christian friend, do not be complacent about your salvation. “Therefore, let him who thinks he stands take heed lest he fall” (1 Cor. 10:12). Like Israel, we too can commit sin. When we continue in sin, refusing to repent to be forgiven, our names will be removed from God’s Book of Life. Be faithful to follow Jesus and do not walk in darkness, “but have the light of life” (Jno. 8:12).
