15 I urge you, brethren—you know the household of Stephanas, that it is the firstfruits of Achaia, and that they have devoted themselves to the ministry of the saints—
16 that you also submit to such, and to everyone who works and labors with us.
17 I am glad about the coming of Stephanas, Fortunatus, and Achaicus, for what was lacking on your part they supplied.
18 For they refreshed my spirit and yours. Therefore acknowledge such men.
first fruits (v.15) — the first believers in Corinth and their relationship to those who believed after them
devoted (v.15) = addicted — to serving others in the church
what was lacking (v.17) — the men evidently brought supplies and/or money which the church in Corinth itself should have supplied
refreshed my spirit and yours (v.18) — probably, on Paul’s part, by bringing news from Corinth and on the Corinthians’ part, by giving him that news so he would have the truth about them and not be misrepresented
such men (v.18) — those who serve the saints. Here, Paul says to recognize them. Earlier (v.16) they are told to submit to these men in the area of giving.
