Um, if it was a job, they’re legally obligated to pay you. If we’re talking about God’s view on it, if they said they would pay you and didn’t, that’s in violation of God’s word. Of course we do ultimately have forgiveness through the blood of Christ, but sin unto death is a thing, and if they continue to do things like that without repentance or seeing anything wrong with it, then yes it’ll be on them. And for Christians the proverbial bar is higher because we literally have the Bible as our book to live by, so we can’t say we didn’t know better.
