“And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.” (Romans 12:2, KJV 1900)
For most, coming to and discerning one’s “calling’ is by no means an overnight process; Rather, for believers and unbelievers alike, it is lifelong—whether one is pursuing it or not. And perhaps one sure way of searching forward to discover one’s “calling” and the “will of God” is to begin by searching backwards to “prove what is that good, acceptable and perfect will of God.”
To be clear, one cannot develop a formulaic, mathematical and rational approach for discerning the “calling” that this writer believes every person possesses. (And it is unique and it is not to be compared to another except insofar as it conforms–albeit far from it–from the Lord. Read Hebrews 5:8-10.) Chiefly there is a call to the Lord and secondarily to one’s purpose here in the earth in response to Him: “For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.” Isaiah 55:9 (To even attempt to address such a wide chasm between our own understanding and His can often appear unknowable and it necessitates first and foremost a personal relationship with the Creator.)
All the same, there are several principles that we might glean from in helping us to discern “calling” and one of these is “proving” in Romans 12:2 which contextually occurs —similar to the call of Isaiah—in the prior verse Romans 12:1. Like Isaiah, one’s “reasonable service” is confession, separation and ongoing commitment that precedes discovering “calling” See my commentary on Isaiah’s calling: https://intersectionoffaithandlearning.com/2025/09/09/send-me-a-commentary-on-calling/
“Proving” involves finding evidence for, having witnesses to, and objective (not opinion) facts that give transparent confirmation to an assertion. And one way to discover one’s calling is to observe and prove (for one’s self) attributes, giftings, passions, interests, successes, talents etc that have been resident with you since one’s youth. (It is never too late to undertake and fulfill one’s highest “calling to God” and one’s secondarily “calling” concerning what you are to do in response to this “calling.”)
Notwithstanding, this “proving” (as with most principles) contains 3 important constraints when considering them within a perceived “calling”. These might be framed into the following queries: “Is it good?” “Is it acceptable?” “Is it perfect?” (The latter being does it possess the intrinsic and latent qualities of a talent or giftedness that has been given to you effortlessly and was not obtained on one’s own.) This would be akin to a fish being created to swim and not climb a mountain like a mountain goat.
It would be beyond the scope of any single commentary to begin to determine those “good,” “acceptable,” and “perfect” things that have been given to us for “calling” in “service” to others which is part and parcel of everyone’s “purpose.” Yet one singular place to begin discerning whether one is in “lockstep” with one’s “calling” is “proving” what has preceded (and perhaps overlooked) in the past to determine how to bring forth “calling” in the present.
