Does God always remove his wrath when an individual repents? 2 Kings 21-25

2 Kings 23:24-26 (NASBStr)

Moreover, Josiah removed the mediums and the spiritists and the teraphim and the idols and all the abominations that were seen in the land of Judah and in Jerusalem, that he might confirm the words of the law which were written in the book that Hilkiah the priest found in the house of the Lord. Before him there was no king like him who turned to the Lord with all his heart and with all his soul and with all his might, according to all the law of Moses; nor did any like him arise after him.

 However, the Lord did not turn from the fierceness of His great wrath with which His anger burned against Judah, because of all the provocations with which Manasseh had provoked Him.

There is a false premise in the minds of most Christians that God forgives indefinitely with no consequences for sin.    And, whereas, the fact that God has forgiven and forgotten our sins as far as the east is from the west, the above passage teaches us another aspect of God's forgiveness.   Josiah, if you read chapters 22-24 was one of the most righteous kings in Judah.  He heard God's Word, responded with a revival, and, yet, God still imposed judgement on the nation of Judah.  These are God chosen people.   These are people who had the promises, the temple, the covenants, the miracles (Romans 9:1-6).    Yet, their repentance was too late.  They had to suffer the consequences for their years of no repentance.   God is faithful to forgive.   But, God can't forgive if we don't repent and allow His Son and Spirit to cleanse us.   Josiah was repentive in his life.  However, his repentance was not matched by the nation prior or after.  God's grace was apparent in Josiah's day and that held off God's wrath.   However, God does not forgive when there is no confession of sin and repentance.   Individually we can see God's grace and mercy stay off the wrath deserved for gross sin.   But, this was not an individual problem.  This was a national problem.   Individual believers can hold off God's wrath and see God's grace flow into the world.  But, once those individuals are gone, the wrath of God will flow once again.   God always forgives when we claim the substitutionary atonement of His Son.    But, we must never expect God to forgive when we lack repentance and continue in our sin.
