I started thinking recently about the idea behind the book of Malachi. While I've been preaching from there, I've emphasized the concept that this was God's last word to His people before a long period of silence from heaven.
His message then, was to hold Israel to a spiritual perspective until the coming of the Messiah. When I then see how the Gospel writers characterized the religious leaders of Jesus' day I have to wonder if Malachi's oracle had the effect intended. It doesn't seem to have kept Israel tracking closely with God.
