As I’ve often talked about (and I’m sure you already know), you cultivate what you honor.
So if your college ministry prioritizes disciplemaking/mentoring (whether one-on-one or small group), then here’s a particular and peculiar way to honor that – and to cast a vision for value in the process.
What if you recognized those whose impact has traveled generation-to-generation through your college ministry? Surely (if you’ve been prioritizing these forms of discipleship) you can trace “lineages” of disciplemakers-and-disciplees: That senior whose small group from two years ago spawned a few small group leaders. That one-on-one gal who (just as you encouraged) raised up ladies who discipled other ladies… who in turn discipled other ladies (a la II Tim. 2).
Maybe you’d even recognize (in-person or in-picture) alumni whose legacy is one of impact. Depending on the history of your ministry, it’s very possible that some of your current leaders can (with your assistance and some major research) trace their “disciplemaking genealogy” back to some who’s in their 40s now (or older). How awesome would it be to come up with ways to recognize that heritage?
On the far end of this idea there are likely concerns to watch out for: competition, hero-worship, shame for those whose lineages are “broken,” etc. But we shouldn’t avoid possibilities because of potential, avoidable problems. And again, we’ll all cultivate what we honor, so if this isn’t how your campus ministry energizes and rewards multi-generational discipleship, what is?
