Yes, the problem is our sin; yes, we need to be forgiven of sinfulness and our sins. But that sin and that forgiveness are connected to our lordly assignments and to our priestly responsibilities and to our flailing and failing attempts to usurp God’s tasks to make them ours. The only one worthy to sit on that throne is King Jesus.— The King Jesus Gospel, pages 141-142
It definitely is an exclamation point, but I also think an interrobang accurately expresses the surprise that most felt at what God has done. My own response when I encountered the unconditional love, forgiveness, and new life in Christ was definitely an interrobang—"He loves me?" and, "He loves me!" in a cosmic mash-up whose repercussions are still being felt in my life 42 years later. Praise to Him!
