Some people like to make excuses. They would rather blame the circumstances that they are put in a rather than step up and make them better.
In 2 Chronicles 29, it is a good thing that Hezekiah was not like that. He inherited Judah in a pretty sad state after the mess that Ahaz made. Nevertheless, he immediately got around to taking steps in the right direction.
2Ch 29:5 and said to them, “Hear me, Levites! Now consecrate yourselves, and consecrate the house of the LORD, the God of your fathers, and carry out the filth from the Holy Place.
2Ch 29:6 For our fathers have been unfaithful and have done what was evil in the sight of the LORD our God. They have forsaken him and have turned away their faces from the habitation of the LORD and turned their backs.
It is kind of sad that the people of Judah allowed such a beautiful building that served such an important purpose to fall into utter disrepair. We find out later that it took all of the priests that were there 16 days to entirely clean everything out.
That is a pretty major job, but it is one that Hezekiah wanted to be done.
He could have simply folded up and not done anything. The generation before that made such a mess that maybe trying to clean up and make everything better could have taken too much effort. The status quo would have certainly been easier.
Regardless, he knew that that was not a good response. He knew that the house of God needed to be a place that would indeed honor God. Not only that, but he was happy about the end result.
2Ch 29:36 And Hezekiah and all the people rejoiced because God had provided for the people, for the thing came about suddenly.
He knew that God was with them and was helping them. It seems like that made all of the effort worthwhile.
