Law

See, I have set before you today life and prosperity, death and adversity.

 If you obey the commandments of the LORD your God that I am commanding you today,  by loving the LORD your God, walking in his ways, and observing his commandments, decrees, and ordinances, then you shall live and become numerous, and the LORD your God will bless you in the land that you are entering to possess.
Deuteronomy 30:15-16
