The book of Second Chronicles parallels First and Second Kings but ignores Israel because of its false worship and refusal to acknowledge the temple in Jerusalem. The temple and temple worship, is central throughout the book, benefits a nation whose worship of God is central to its very survival.
The Book of Second Chronicles provides histories of the end of the united kingdom (Solomon) and the kingdom of Judah. Chronicles is a divine editorial on the spiritual characteristics of the Davidic dynasty. This is why it focuses on the southern rather than the northern kingdom. Most of the kings realize that apart from the true mission of a covenant nation, failing to call others to Yahweh, Judah had no calling on her own. Only what is done in accordance with God’s will has any lasting value.
