I've waded through the first nine chapters of Chronicles--the one part of the Bible that bogs me down more than Leviticus. I've gone over a rehashing of all the kings of Judah: So-and-so did right but... Then, so-and-so did wrong and...
Finally, I come to Hezekiah (II Chron. 29 & 30). After the sixteen very evil years of his father, Hezekiah immediately returns the people to worshiping God. But no one is ready. They have to put off the Passover for a month and it is still messy and chaotic. I can just imagine the questions from those who don't remember how to celebrate it. They fail to follow all the rules.
But they come eagerly, in honesty and sincerity. Some travel from the far parts of Israel despite the ridicule of their neighbors. They throw themselves on God's mercy and He forgives the messiness, the wrongness, even their sin. They celebrate. With joy. For two weeks instead of one.
What a picture of God's grace! What a story of hope for restoration.
And what an invitation to come - to a God Who now has offered the final Passover and made us ready so that no one need be "unprepared."
