Be kind and tenderhearted to one another, forgiving each other. So far this reads like general good advice, the sort of thing nobody argues with and nobody does.
Then comes the clause that changes it. Just as in Christ God forgave you.
That is the standard, and it removes the calculation most of us are quietly running. We tend to forgive proportionally, measuring the offense, whether they seem sorry, whether they would do it again. Paul cuts that entirely and replaces it with a single comparison that has nothing to do with them.
What happened to you is the measure. And what happened to you arrived, if you remember, before you had cleaned anything up.
Tenderhearted is a strange word to find in a command. It suggests softness is something you can choose rather than only something you feel. You can decide not to harden, today, in one specific case.
Start with whoever came to mind while you were reading this.
