I'm not religious, but I grew up in a religious home. It's worth noting that "everything happens for a reason" and "God has a plan for everything" are not in the Bible and are not doctrine, as far as I remember. These are platitudes people with a poor understanding of their religion say, but not actually part of the belief system. This pastor likely has a more nuanced, and possibly more painful, view of this event through the lens of their belief.
