Sincerity is not the issue, truth is the issue verse.
Related to the previous concern, we live in a very visual day and age. This means that a show like The Chosen will reach many people that would not necessarily pick up a Bible. But the danger with this is that their understanding of who Jesus and the disciples were may be tainted by the show. It may encourage “reading things into” the gospels that aren’t there or overly-personalizing different elements of the Bible when that is not the scriptural intent. As a pastor friend of mine once said, “Do we get excited about going to the Word as much as we are excited for the next episode to come out? Or have we gotten lazy and apathetic?” Those who brush this concern aside shouldn’t. Art is a powerful thing and we should be careful to allow Scripture to critique the shows we love, not the other way around.
