God calls Himself a jealous God to express His holiness and exclusive right to the worship and devotion of His people. He threatens punishment for those who hate Him and disobey His commandments, including physical death and eternal damnation. He threatens to punish descendants for the sins of their fathers to motivate fear of His anger and obedience to His commands. However, He promises blessings of His constant love and goodness to those who believe in Him and keep His commandments, both in this life and the next.
