Phil 2:14 Do everything without complaining or arguing (NIV), Do all things without grumbling or questioning (ESV), Do all things without grumbling or disputing (NASB), Do all things without murmurings and disputings (KJV).
I’m not sure… but I don’t think there’s a caveat in that verse. I don’t think I read an exception clause either. It may be that I’m missing something, but I don’t there there is a time when it is acceptable to whine, gripe, or complain about what you do OR are asked to do.
Short verse… short post… lengthy reflection.
