It can be difficult to work through Chronicles. In many ways, the material is a repeating of the history found in Samuel and Kings. But Chronicles is also different. There is a strong focus on genealogical matters. In fact, the first nine chapters are all chronology from Adam to Saul, who died in battle at the hands of the Philistines. And the Lord “turned the kingdom over to David the son of Jesse” (10:14).
When acknowledging David as their new king, the people declared, “And the Lord your God said to you, ‘You shall be shepherd of my people Israel, and you shall be prince over my people Israel’” (11:2). Whoa, this language – “shepherd of my people” and “prince over my people” – sure seems reminiscent of another, doesn’t it? Well, of course! Here is an intense interest in and focus on the historical family lines that converge in David. And this makes sense, for the story of the Bible, ultimately, is the story of the Messiah, who is the direct descendant of David, and before him, a descendant of Adam. He is the very one foretold in Genesis 3:15, a descendant of Adam and Eve, who would defeat Satan and sin and death. It's an amazing story, and one that never gets old. In the meantime, David’s mighty men gathered around him and they defeated all their enemies as the Lord game them victories. The Lord was on their side, and he is on our side.
Who is on the Lord’s side? Who will serve the King?
Who will be His helpers, other lives to bring?
Who will leave the world’s side? Who will face the foe?
Who is on the Lord’s side? Who for Him will go?
By Thy call of mercy, by Thy grace divine,
We are on the Lord’s side—Savior, we are Thine! -- Frances R. Havergal (1877)
