Eph 4:11-12, 11 And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, 12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ,
Paul in continuation gives instances of Christ giving gifts to men. Of those gifts were various offices. The object of all these offices was to promote “the unity of the faith”.
Rom 12:4-6, “4 For as in one body we have many members, and the members do not all have the same function, 5 so we, ... 6 Having gifts that differ according to the grace given to us, let us use them…”
The physical body’s complexity is mind boggling, each part works in impeccable harmony where there are no abnormalities, sickness, injuries etc. The illustration of the members of the body sets forth the mutual dependence on each other as a picture of members of the Church with their several gifts and functions for the well-being of the whole body. 1Pe 4:10, “As each has received a gift, use it to serve one another, as good stewards of God’s varied grace 11…in order that in everything God may be glorified through Jesus Christ.”
It is imperative that we desire these gifts for one purpose, to be equipped to edify for the sake of unity, 1Co 14:12 “Even so you, since you are zealous for spiritual gifts, let it be for the edification of the church that you seek to excel.”
