What are the effects of national repentance?

Jason Dohm explains in this video when a nation repents, the idols begin to be smashed. In Israel, they had gone so far in decline. When the nation begins to reform, we will see idols begin to fall. The idols that take the place of God will fall. 

The idols of our nation today are served and loved by many today. When this nation begins to repent, we will begin to see those idols dealt with. 

2 Chronicles 7:14 (NKJV) – “If My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land.” 

When a nation repents, the idols begin to be smashed. We see this happen at various points in Israel's history where they've gone so far into decline that you would think that maybe they would never come back but God would raise up a man or families or a generation that saw the problems and that actually turned away from the wickedness and turned to trusting and hoping in God. And when that happens, the idols that have been served and loved and taken the place that God should have had, they come down, they're dealt with. And I'm praying that we'll see that in our nation. I think the idols of our nation are obvious.

And they are loved and they are served by the majority of our countrymen. And when this nation begins to repent and be reformed, we'll see those idols be dealt with.
