While in the past chapters we have seen a prophecy against Tyre as a nation and how God has turned His back on the nation and that the structures and institutions of the Tyre will come tumbling down. This chapter is dedicated to speaking out against the ruler of Tyre, the king of Tyre. It is really interesting how God speaks incredible praises about this king. He was a "signet of perfection". I don't think those words were reserved for anyone else, much less one who was considered outside of the people of God.
The reasoning behind the destruction of the king is seen a few times where we read: "your heart is proud" in verses 2, and in vs.5 where because of that pride God will bring strangers against him. Once that declaration is proclaimed then God extols the king as someone who could have been a contender, someone who could have been someone special. Look at vs.15 where we read: "You were blameless in your ways from the day that you were created, until iniquity was found in you." Basically what we read is that you were perfect until we started looking for imperfections.
One of my favorite quotes is that a saint is someone whose past has not been examined enough. That is so true, each of us has sinned and fallen short of the glory of God. But thanks be to God that we have Jesus who has taken our sin and claimed it as his own so that we can have eternal life.
