2 Chron. 28-30
King Hezekiah instituted a massive process of restoring God’s temple and worship according to the law and the way that David had served the Lord. This was greatly pleasing to the Lord. A tall order in this process was the ceremonial cleansing of the priests and Levites. They couldn’t just walk in and begin their service without becoming clean in their life and practices. God was picky about who stood before Him to minister. Remember, King Uzziah was stricken with leprosy as he presumptuously ministered to the Lord in his uncleanness.
The application to us is that God does desire us to live clean lives. A quest for purity of heart was commended by Christ Jesus … He said the pure in heart would SEE the Lord.
