19 I call heaven and earth as witnesses against you today that I have set before you life and death, blessing and curse. Choose life so that you and your descendants may live, 20 love the Lord your God, obey him, and remain faithful to him. For he is your life, and he will prolong your days as you live in the land the Lord swore to give to your ancestors Abraham, Isaac, and Jacob.” (Deuteronomy 30:19-20)
Choose Life (19): This is a repetition of what has gone before: Life and death, blessings and curses. The command is to choose life through obedience. The Lord pointed to his creation (heaven and earth: power in storms and earthquakes instead of peace and calm) as a guarantee that what he said would happen if the people were disobedient. (Ancient covenants often contained a list of gods as witnesses.) It was a choice; a choice that they needed to make. Their decision would affect not only their lives but the generations to come.
Total Commitment (20): Moses concluded his sermon by urging them to be totally committed in three ways: (1) love the Lord, (2) obey the Lord, and (3) remain faithful. They were to keep his commands close to their hearts and the Lord would provide life. He was the cornerstone of their existence. Further, he was about to fulfill his promise to give them a land of their own. Notice the new covenant parallel: by choosing to believe the Lord’s promise of salvation, we will be given eternal life and the indwelling Spirit. He is our cornerstone. The promise of both the old and new covenants is life. In both cases a decision is required. Then the battle begins. For the Israelites it was eliminating the pagan influence. In our case that means changing the way we think and act. Choosing God is to choose life.
Challenge: Have you chosen life? Are you totally committed to the Lord? Are you experiencing the blessing of total commitment?
