Is Thessalonians intended to address us all, or merely those Thessalonians who actually learned of it?
Your effort to use "have learned" as a time lock fails on its face.
If Thessalonians, or any of Paul's letters, was intended to address only a particular group at a particular time and had no further relevance they would not be part of Scripture. Scripture, all Scripture, is intended for all.
Your effort to use "have learned" as a time lock fails on its face.
One word comes to mind. STUPID!
