Peter addresses both groups in these verses.
Everyone has some gifts; find yours and use them.
All our abilities should be used in serving others; none are for our own exclusive enjoyment.
Peter mentions speaking and serving.
1 Peter 4:10-11 God has given each of you a gift from his great variety of spiritual gifts. Use them well to serve one another. Do you have the gift of speaking? Then speak as though God himself were speaking through you. Do you have the gift of helping others? Do it with all the strength and energy that God supplies. Then everything you do will bring glory to God through Jesus Christ. All glory and power to him forever and ever! Amen.
