Judah gets two more kings: one bad and one good. We are told the only reason God does not depose Ahijah is because of His promise to David. Fortunately, Ahijah is followed by a good king named Asa.
It is fascinating to see bad followed by good. We typically think good parents raise good children and bad parents raise bad children. There are many examples in the kingly line of Judah that break this pattern. Children can grow up in ways that are hard to explain simply with parenting. We should pray for our children and the children we know. We want them to grow up to be people who follow God.
