The words "your apostles" also appear to be used with design. They contain a direct acknowledgment of the mission of St. Paul as an apostle. By him more than by any other had these regions been brought to the knowledge of Christ, and we may rest confident that the gospel which he preached elsewhere he preached to them also. The lesson of watchfulness is oft repeated in his letters. To the Corinthians he writes, "Watch ye; stand fast in the faith; quit you like men; be strong" (1 Cor. xvi. 13), while, in connexion with this subject of the day of the Lord, his words to the Thessalonians are, "Ye yourselves know perfectly that the day of the Lord so cometh as a thief in the night.... But ye are not in darkness, that that day should overtake you as a thief. Let us watch and be sober" (1 Thess. v. 2-6). St. Peter's letter was to be read in those Galatian Churches whose members in past days had doubted about the apostolate of St. Paul. Its warnings would sink the deeper because enforced by the authority of him who even in his rebukes had spoken to them as his "little children" (Gal. iv. 19). _Knowing this first, that in the last days mockers shall come with mockery._ St. Peter says the mockers will come; Polycarp[14] says in his day they had come. He terms them the first-born of Satan, and tells how they pervert the oracles of the Lord to their own lusts and deny that there is either resurrection or judgement. The signs of the times were not difficult to read; and the Apostle would have the brethren know what to look for, know in such wise that they should not be shaken in mind by what they saw or heard. For this the first need was Christian sobriety. Thus settled, they could ponder on the words of ancient prophecy and recall the lessons of those who had spoken to them in the name of Christ; and therewith their hearts might take comfort, and their heads be lifted up with expectation, knowing the last days were bringing their redemption nearer. The mockery of the sinners would keep no bounds. This he expresses by his emphatic words, just as largeness of blessing is described: "In blessing I will bless thee." [14] _Ad Phil._ vii.
