All the old is gone and dead, everything is new. We who were once far off have been brought near. God took the initiative. And God entrusted to us the treasure of bearing the message of reconciliation. Paul uses a great metaphor for us as ambassadors.
Ambassadors represent a foreign ruler.
Although, we are cultural exiles in our own land today, we nevertheless are ambassadors of the King of Kings and the Lord of Lords. Our call is to announce our king's amnesty to the people. When we lived in the Philippines we heard the story of the Ambassador to Japan being stopped on the streets of Manila by two robbers. Of course, they didn't know. But his response was so startling they didn't know what to do.
