A Blessing and a Curse
Behold, I set before you this day a blessing and a curse; A blessing, if ye obey the commandments of the Lord your God, which I command you this day: And a curse, if ye will not obey the commandments of the Lord your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.
- Deuteronomy 11:26-28 (KJV)
We should keep the commandments of God.
It's that simple really.
