10 As each one has received a special gift, employ it in serving one another as good stewards of the manifold grace of God. 11 Whoever speaks, is to do so as one who is speaking the utterances of God; whoever serves is to do so as one who is serving by the strength which God supplies; so that in all things God may be glorified through Jesus Christ, to whom belongs the glory and dominion forever and ever. Amen. 1 Peter 4:10-11
A lot can be taught on the subject of spiritual giftedness. Perhaps do it right and study Paul’s lists (Romans 12:6–8, 1 Corinthians 12:8–10), or the passage above. You could take the easy route, and take an “assessment test” to “discover” your gift, but I happen to think it should be obvious. That’s why I like Peter’s explanation for starters, and it goes something like this.
Gifts are given by his grace and for his glory. They either involve speaking or serving. They’re to be employed responsibly, to the fullest extent possible, to minister to other Christians. They’re noticeable when someone serves with superhuman strength or speaks in sentences that could be uttered by God.
So as you serve, if you accomplish something that you can’t believe you did, or say something that you can’t believe you said, then it’s likely because you used your gift. Then your response must always be, to God be the glory.
