There's an ancient legend about the city of Rome involving two mysterious characters.
The first was named Mr. Right. He was a bishop from a far away land. He came to explain an ancient document in the land of Rome. It had been penned by a martyr about two millennia prior.
For many years, the people of Rome had come to believe the letter spoke about how a person was to be brought into a right relationship with the King. They believed it expressed hope in someone who had purchased justice for them at the price of his own blood. They thought it described them as guilty and needing to be declared innocent. They thought it was a story about another doing a great work that could be credited to their account.
But Mr. Right arrived to correct them. Instead, he said, no my friends, this is a story about exiles coming home. It's a story about enemies of the people, enemies that have been defeated. All you need to do is come home through the work of the enemy-killer. When you get there, he'll put a sign on you that says "you're in." There's no transaction, no credit, to purchased justice. It's a declarative statement that you're already in.
Moments later, a mysteriously dressed Piper, arrived and bellowed out a tune unsuitable for most ears, but compelling to some. This Piper said, "If all that occurs is a declarative statement, that "you're already in," then why do you need to come in at all? Beware of Mr. Right, warned the Piper. You are guilty, and the King is angry. You're worse than exiles; you are enemies. Either you die for your enmity or you believe in the One who died for your enmity. This One is the very Son of the King. Either you take what He earned or get what you earned. There must be a transaction, a gift of credit, and purchased justice. Listen to this tune. Do not tune this out.
As the legend goes, Mr. Right led some on a journey far from where any had traveled before. In like manner, the Piper convinced some as well. Where these mysterious figures will take their convinced crowds is only known by the great King. All that's left is that ancient Roman document...how will we read it? What does it really say?
