Does the Bible ever instruct us to “identify our gift(s)”? Or rather, does it simply assume one will know their gifting, and instruct us more on the reason they are giving (i.e., edification)?

I don’t want to argue that identifying one’s gift is unimportant. If you don’t know where you are gifted, that may create barriers to utilizing those gifts (alternatively, you might just end up using them intuitively without fully realizing it). My point, though, is, “identifying” gifts just doesn’t seem to be an emphasis in the scriptures anywhere. This sort of talk, I worry, can treat Spiritual gifts almost like some otherwise mysterious thing we need to diagnoses through a series of tests. I tend to think it’s not that complicated. I think Paul and Peter are more likely just saying, “Hey, God’s gifted you all in different ways to serve each other. Now go do that.” The focus is on the using of gifts–as if their identity is somewhat obvious to all–not the identification of them, as if that’s something still needing to be done.

But again, that’s not to say that in some cases it’s not helpful to help someone recognize the ways God has gifted them.
