God chooses whom He will choose to lead.

“When Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the royal heirs. But Jehosheba, the daughter of King Joram, sister of Ahaziah, took Joash the son of Ahaziah, and stole him away from among the king’s sons who were being murdered; and they hid him….,,Then the escorts stood, every man with his weapons in his hand, all around the king, from the right side of the temple to the left side of the temple, by the altar and the house. And he brought out the king’s son, put the crown on him, and gave him the Testimony; they made him king and anointed him, and they clapped their hands and said, “Long live the king!” Then Jehoiada made a covenant between the Lord, the king, and the people, that they should be the Lord’s people, and also between the king and the people. And all the people of the land went to the temple of Baal, and tore it down. They thoroughly broke in pieces its altars and images, and killed Mattan the priest of Baal before the altars. And the priest appointed officers over the house of the Lord. Then he took the captains of hundreds, the bodyguards, the escorts, and all the people of the land; and they brought the king down from the house of the Lord, and went by way of the gate of the escorts to the king’s house. Then he sat on the throne of the kings. So all the people of the land rejoiced; and the city was quiet, for they had slain Athaliah with the sword in the king’s house. Jehoash was seven years old when he became king.”
