2 Chronicles 24:20 And the Spirit of God came upon Zechariah the son of Jehoiada the priest, which stood above the people, and said unto them, Thus saith God, Why transgress ye the commandments of the Lord, that ye cannot prosper? Because ye have forsaken the Lord, he hath also forsaken you.
After the death of Jehoiada, Joash listened the wrong advisers, and the people left God’s house and served groves and idols. The Lord sent prophets to them, but they would not listen. Then the Spirit of the Lord spoke through Zechariah. They transgressed the Commandments, especially the First. Therefore, they could not prosper. And they forsook the Lord. Therefore, the Lord has forsaken them.
Things go well in life when the one true Lord and God is believed, put first, and worshipped. Things do not go well when other gods and things are trusted in instead of God alone. Joash was the last of the good kings, but his reforms did not last long or go far enough, at least according to Jeremiah and the prophets. After Joash the kingdom did not last much more than twenty years as Babylon destroyed Jerusalem and the Temple and took the people into captivity.
We also need to respond to our problems by turning back to God daily, for indeed we daily sin much and deserve wrath and punishment. But we repent often and believe again the grace of God in Christ. We respond to that Gospel by putting God first, worshipping Him alone, and forsaking the sinful world and the sinful self.
