29:20-36 As soon as Hezekiah heard that the temple was ready, he lost no time. Atonement must be made for the sins of the last reign.

It is not enough for us to be where God is worshipped, if we do not ourselves worship with the heart. And we should offer up our spiritual sacrifices of praise and thanksgiving, and devote ourselves and all we have, as sacrifices, acceptable to the Father only through the Redeemer.Hezekiah addresses, not the priests, but the congregation: "Now that by the atoning sacrifice which has been offered for you, you are consecrated once more to be a holy people to the Lord, approach with confidence and offer your free-will offerings as of old."
