2 Chron 17-19 Asa may not have been the perfect king, but it seems he did one thing right; he raised a godly son named Jehoshaphat, who took his place. Each of us is responsible for following God or not but our parents have much to do with our path. Asa’s son cleansed the land and brought about many godly reforms. We aren’t told about his heart but we “know” him by his fruit. [Matt 12]
However, Jehoshaphat had one glaring fault: he allied with King Ahab, who was a narcissist to the core. When Ahab wanted to fight a war, he urged Jehoshaphat to go to war with him. To his credit, Jehoshaphat wanted advice from a prophet before he went. Ahab, the ever-present fool, called in his false prophets who would agree with him whether right or wrong. Jehoshaphat was discerning enough to ask for a godly prophet to give his advice, which turned out to be accurate to the last jot and tittle while the false prophets’ words fell to the ground. Ahab was killed in battle even after disguising himself. Galatians 6 reminds us God will not be made a fool.
Jehoshaphat, to his credit, called for godly advice before he set out. We should do the same. “But if anyone is deficient in wisdom, he should ask God, who gives to all generously and without reprimand, and it will be given to him.” [James 1:5]
