Peter encourages each of us to “use them well to serve one another” (1 Peter 4:10). If you keep your talent or ability to yourself, then I suffer, just as you suffer if I don’t serve you with the gifts God has given me. I would be nowhere if people didn’t share their gift of DIY - the ability to repair things - because God hasn’t given me that gift! But God has given me the ability to preach and teach his Word, and I am grateful that people encourage me that they are blessed when I use that gift.
