“That the man of God may be complete, equipped for every good work.” (2 Tim. 3:17)

“But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.” (1 Peter 2:9)

“And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ,” (Eph. 4:11-12 ESV) 

Therefore

“As each has received a gift, use it to serve one another, as good stewards of God's varied grace:” (1 Peter 4:10 ESV)
