Ephesians 4:15-16

But speaking the truth in love [in all things—both our speech and our lives expressing His truth], let us grow up in all things into Him [following His example] who is the Head—Christ. From Him the whole body [the church, in all its various parts], joined and knitted firmly together by what every joint supplies, when each part is working properly, causes the body to grow and mature, building itself up in [unselfish] love.
