5:12 {14} By Silvanus, a faithful brother unto you, as I suppose, I have written briefly, exhorting, and testifying that this is the true grace of God wherein ye stand.

(14) Continuance and perseverance in the doctrine of the apostles is the only ground and foundation of Christian strength: Now the sum of the apostles doctrine, is salvation freely given by God.

5:12 By Silvanus. Silas, the old companion of Paul. It has been supposed that Paul, then a prisoner of Rome, had sent Silvanus to Peter.

Our faithful brother to you, as I suppose. This implies that Peter had little personal acquaintance, Silvanus having been with Paul in the work among the Gentiles.

I have written briefly. He sends this letter by Silvanus.

This is the true grace of God wherein ye stand. The gospel which had been preached to them.

5:12 As I suppose - As I judge, upon good grounds, though not by immediate inspiration. I have written - That is, sent my letter by him. Adding my testimony - To that which ye before heard from Paul, that this is the true gospel of the grace of God.

5:10-14 In conclusion, the apostle prays to God for them, as the God of all grace. Perfect implies their progress towards perfection. Stablish imports the curing of our natural lightness and inconstancy. Strengthen has respect to the growth of graces, especially where weakest and lowest. Settle signifies to fix upon a sure foundation, and may refer to Him who is the Foundation and Strength of believers. These expressions show that perseverance and progress in grace are first to be sought after by every Christian. The power of these doctrines on the hearts, and the fruits in the lives, showed who are partakers of the grace of God. The cherishing and increase of Christian love, and of affection one to another, is no matter of empty compliment, but the stamp and badge of Jesus Christ on his followers. Others may have a false peace for a time, and wicked men may wish for it to themselves and to one another; but theirs is a vain hope, and will come to nought. All solid peace is founded on Christ, and flows from him.
