12 I'm sending this brief letter to you by Silas, a most dependable brother. I have the highest regard for him. I've written as urgently and accurately as I know how. This is God's generous truth; embrace it with both arms!
New King James Version
12 By Silvanus, our faithful brother as I consider him, I have written to you briefly, exhorting and testifying that this is the true grace of God in which you stand.
New Living Translation

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.
