There are differences of ministries, but the same Lord. 

Azmaveth the son of Adiel was over the king’s treasuries; and Jehonathan … was over the storehouses … Ezri … was over those who did the work of the field for tilling the ground … Shimei … was over the vineyards … All these were the officials over King David’s property.God has appointed these in the church: first apostles, second prophets, third teachers, after that miracles, then gifts of healings, helps, administrations, varieties of tongues … One and the same Spirit works all these things, distributing to each one individually as He wills.As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God. If anyone speaks, let him speak as the oracles of God. If anyone ministers, let him do it as with the ability which God supplies, that in all things God may be glorified through Jesus Christ, to whom belong the glory and the dominion forever and ever.
