It is a sign of God’s covenant grace to David that Jehoiada uses David’s own dedication gifts of hundreds of spears and shields to save David’s heir and place him on the throne. Cast your bread upon the waters, for after many days you will find it again. Eccles. 11:1
This is at once, as many of the readings, both a story of great hope and equally great sorrow.
We have a murdering grandma, a faithful priest, and the little boy of the kingly line that the priest saves.
The little boy is crowned, the grandma offed, and the city has peace.
For a while.
Then the faithful priest dies, and the king goes astray. He follows the folly of his ancestor Rehoboam and listens to ungodly words from the fellow royals.
He kills the faithful priests son, whose only crime (not really) was to speak God’s truth to the king. The king who was once the little boy hiding for his life from an evil grandmother.
We _always_ need God. We _always_ need His word, His Spirit, His love and faithfulness in our lives, His mercy and grace.
