That’s like the sort of thing you’d hear from an actual saint or something.
Depends on where you hear it.
Whitlock is from central GA, got private schooling at a Christian school, then went to U.Alabama. He's a publicly self-professed Christian on social media. From the overall context, I'd guess he's chosen a variety of southern born-again faith. In that context, the "servant's heart" is fairly par for the course.
FWIW, I don't think that's determinative of anything. I've met people who mouth concepts like that but are nevertheless privledged, insularly un-civic, and racist. I've also met good people with the same background who truly
do get it, in a very outward-looking and humanity-affirming way.
Personally, I tend to view people making public statements like that as a bit of an intensifier. Either you're using a very powerful concept as cover for a non-examined life, or you're setting a high bar for yourself. I'd be very pleased to find out Whitlock (or anyone) is closer to the latter. As there's nothing to indicate otherwise, I'm inclined to take him at his word. In fact, it's nice to see him reminding himself what matters, in the context of getting some long-term financial stability for himself and his family.
I wish him the very best, on the field and off it.
