Then We Will No Longer Be Infants Eph. 4:14-16

Then we will no longer be infants, tossed back and forth by the waves, blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming. Instead, speaking the truth in love, we will in all things grow up into Him who is the Head, that is, Christ. From Him the whole body, joined and held together by every supporting ligament, grows and builds itself in love, as each part does its work.

How does each believer contribute to the Body of Christ, the Church?
