#9) Ephesians 4:12

 
"Christ established the Church in order) to equip his people for works of service, so that the body of Christ may be built up

The Church

Christ gave us the Church to give us unity, encouragement, and maturity in the faith (verse 13).  We are to exercise our spiritual gifts (verse 11), and help each other to know and be sure of what we believe.  We're built up through the equipping and the encouragement of our fellow Christians.  This is why He gave us a diversity of gifts, and this should be the goal of the Church. 

The Church should be what promotes us out of being infants in the faith, "tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming" (verse 14).  Instead, we need to "grow up" in the faith (verse 15), and "build up" each other (verse 16).
