264. What were the implications for the Israelites if they accepted or rejected the blessing of God?

For the Israelites, the blessing of God depended on whether or not they obeyed God’s commandments and served Him alone. Disobedience toward God was associated with curse for the people. This decision lay in the hands of the people themselves: “Behold, I set before you today a blessing and a curse: the blessing, if you obey the commandments of the Lord your God which I command you today; and the curse, if you do not obey the commandments of the Lord your God” (Deuteronomy 11: 26-28).
