Verse 12.— By Silvanus, a faithful brother. This is the Silas who traveled and suffered with cour­ageous Paul, and preached to the jailer at Philippi. By him Peter sends this letter, exhorting the brethren and testify­ing as an apostle that the faith of the gospel embraced by the brethren is the true grace of God. It came from God, and is worthy, therefore, of acceptance. All other religions in the world are false.
