Ephesians 5:17-21, Does the Bible say we must give thanks to God for bad things?

There are Christians whose interpretation of this is rigidly literal– they will tell parents who have lost a child,• even if it feels wrong or is difficult to do, they must give thanks• “It’s what the Bible says, so that’s what you must do”– since this is their belief,• they have to somehow justify this practice◦ the authoritarians might say, “God moves in mysterious ways”◦ the rationalists might say, “Giving thanks changes your perspective”
