In Deuteronomy 11:8-32 Moses concludes his exposition of the First Commandment to have no other gods before Him. As is typical for covenant contexts, he concludes with a blessing and a curse for the people depending on their obedience. The obedience required is loving God and the blessing to be received is life with God in the land. Such an exhortation applies to all people today. You must love God in order to receive the blessing of life with God in the new heavens and new earth.
