The people of Israel were at a crossroads as Moses gave this ultimatum. They could choose to depart from the Lord and do evil. God didn't force them to follow His ways, and He still doesn't force anyone. The Bible records examples of many who departed from the Lord through sin and unbelief. Life is in God.
Death is because of sin.
As we think of the choice before us today, we must realize that we have no strength of our own to come to God, to choose life. But He is attending His Word today, and even as He calls us, He enables us to come. He promises His forgiveness no matter what the past and present may be. Perhaps there is someone who hears these words who has had an abortion. You realize your sin today.
