God speaks to the Jewish remnant through the prophet Haggai, reproaching them for their self-centeredness and admonishing them to rebuild the temple. The people respond with repentance and obedience. God also calls us to acknowledge His priorities by: (1) examining our hearts; (2) trusting God's empowerment; and, (3) committing to action.
We have a saying "Good things come in little packages." This is certainly true when it comes to the Bible. There are short books of the Bible that we may never heard preached, know very little about and think they are insignificant. But they pack a powerful message for us in a little package.
