Christian Faith based approach

There were a couple of things in this first look that rubbed me the wrong way, namely that this is clearly a christian faith based book but based on the cover there and introduction text there is nothing to indicate that as the approach and seems slightly misleading. Also the examples of weathering your "hurricane" ranged from the realistic struggles you should try to work through in marriage (MS, pandemic) and equates that in some way by listing a couple that had an affair as something that strengthened the relationship because they "got through" it.
