“In the first year of his reign, in the first month, he opened the doors of the house of the LORD and repaired them” (29:3). Though King Ahaz of Judah shut the Temple’s doors, his son Hezekiah opened them. From the first year of his reign, Hezekiah made it his priority to repair the Temple, call the priests and Levites to work, and begin holy sacrifices. God’s people rejoiced (29:36) in the revival. Finally, King Hezekiah invited all Israelites to come celebrate the Passover (ch 30), which had been forgotten.
Despite the years of rebellion and idolatry, “the LORD heard Hezekiah and healed the people” (30:20). God is gracious and merciful, quick to forgive when we repent (30:9).
