I am glad of the coming of Stephanas and Fortunatus and Achaicus: for that which was lacking on your part they have supplied.
Watch, stand firm in the faith, act like men of courage and strength. A Christian is always in danger and must be vigilant; the Corinthians faced many threats, their feuds ran high, deceivers corrupted their doctrine, irregularities abounded. By faith alone we overcome the world and keep our ground in temptation; without it we fall.

Commenting on 1 Corinthians 16:13-18
The churches of Asia salute you,.... The Syriac version renders it, "all" the churches.

Verse 17. I am glad of the coming. That is, I am glad that they have come to me at Ephesus. I rejoice that he who was converted by my ministry in Achaia, and who has so long shown himself to be a personal friend to me, and an aid in my work, came where I am. Stephanas. The same person evidently mentioned in the previous verses.
