There is only one Lord, one faith, one baptism,
and there is only one God and Father, who is over us all and in us all and living through us all.
However, he has given each one of us a special gift according to the generosity of Christ.
That is why the Scriptures say, "When he ascended to the heights, he led a crowd of captives and gave gifts to his people."
References for Ephesians 4:8
Notice that it says "he ascended." This means that Christ first came down to the lowly world in which we live.
References for Ephesians 4:9
The same one who came down is the one who ascended higher than all the heavens, so that his rule might fill the entire universe.
He is the one who gave these gifts to the church: the apostles, the prophets, the evangelists, and the pastors and teachers.
Their responsibility is to equip God's people to do his work and build up the church, the body of Christ,
until we come to such unity in our faith and knowledge of God's Son that we will be mature and full grown in the Lord, measuring up to the full stature of Christ.
Then we will no longer be like children, forever changing our minds about what we believe because someone has told us something different or because someone has cleverly lied to us and made the lie sound like the truth.
Instead, we will hold to the truth in love, becoming more and more in every way like Christ, who is the head of his body, the church.
