3:5-9 The ministers about whom the Corinthians contended, were only instruments used by God. We should not put ministers into the place of God. He that planteth and he that watereth are one, employed by one Master, trusted with the same revelation, busied in one work, and engaged in one design. They have their different gifts from one and the same Spirit, for the very same purposes; and should carry on the same design heartily. Those who work hardest shall fare best. Those who are most faithful shall have the greatest reward. They work together with God, in promoting the purposes of his glory, and the salvation of precious souls; and He who knows their work, will take care they do not labour in vain. They are employed in his husbandry and building; and He will carefully look over them.
9. Translate, as the Greek collocation of words, and the emphasis on "God" thrice repeated, requires, "For (in proof that "each shall receive reward according to his own labor," namely, from God) it is of God that we are the fellow workers (laboring with, but under, and belonging to Him as His servants, 2Co 5:20; 6:1; compare Ac 15:4; see on 1Th 3:2) of God that ye are the field (or tillage), of God that ye are the building" [Alford]. "Building" is a new image introduced here, as suited better than that of husbandry, to set forth the different kinds of teaching and their results, which he is now about to discuss. "To edify" or "build up" the Church of Christ is similarly used (Eph 2:21, 22; 4:29).
