This promise is a warning. It is God's answer to Moses' prayer. The children of Israel had lapsed into idolatry and were worshipping the golden calf. Moses loved these people so much that he asked God, if He could not forgive them, to blot his name out of the book of life. Then came these words of warning promise, which show that some whose names are in the book of life will be blotted out of that book.
Is my name written there,
On the page white and fair?
In the book of Thy kingdom,
Is my name written there?
__Mrs. M. A. Kidder
May it not be well to pray these words once in a while? Sin against God must be very terrible if it causes our names to be blotted from His book. Sin is not only important; it is deadly. When H. M. Stanley was pressing his way through the forests in the heart of Africa, his most formidable foes, those who caused most loss of life to his caravan, were not the giant tribes, but the small Wambutti. Those little men had little bows and arrows that looked like children's playthings, but upon those tiny arrows was a small drop of poison that would kill an elephant or a human.
Sin may seem little, but it is not unimportant. Unless forsaken, it will bring us to eternal loss.
Jesus said to His disciples, "Rejoice, because your names are written in heaven" (Luke 10:20). How did they know they were there? Because they had forsaken their sins. The promise is: "I have blotted out, as a thick cloud, thy transgressions, and, as a cloud, thy sins" (Isa. 44:22). Let us confess and forsake every sin today.
MEDITATION PRAYER: "I will declare mine iniquity; I will be sorry for my sin" (Ps. 38:18).
