(Now this expression, “He ascended,” what does it mean except that He also had descended into the lower parts of the earth? He who descended is Himself also He who ascended far above all the heavens, so that He might fill all things.) And He gave some as apostles, some as prophets, some as evangelists, some as pastors and teachers, for the equipping of the saints for the work of ministry, for the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. 

Ephesians 4:9-14 (NASB).
