Then we will no longer be infants, 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.
Instead, speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ.Ephesians 4:15 NIV
until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.Ephesians 4:13 NIV
