Receiving God’s Word amid Persecution
Paul thanks God that the Thessalonians received the apostolic proclamation not merely as a human message but as God’s word at work in believers. Their suffering links them with the churches in Judaea that had also faced opposition.
Where this fits in the story: Scripture repeatedly shows God’s messengers opposed, from the prophets through Jesus and the apostolic mission. Verse 16 also appears to reuse an older judgment picture. Genesis 15:16 says the iniquity of the Amorites was “not yet full”; Paul says opponents “fill up their sins alway” before wrath. This is best treated as an Old Testament allusion to accumulated sin reaching judgment, not as a new doctrine about an ethnic group.
