Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time;

 Peter bears witness that what he has written is indeed the grace of God, and he bids his people, amidst their difficulties, to stand fast in it. He says that he has written through Silvanus. The Greek phrase (dia, G1223, Silouanou, G4610) means that Silvanus was his agent in writing. Silvanus is the full form of the name Silas and he is almost certainly to be identified with the Silvanus of Paul's letters and the Silas of Acts. When we gather up the references to Silas or Silvanus, we find that he was one of the pillars of the early church. Along with Judas Barsabas, Silvanus was sent to Antioch with the epoch-making decision of the Council of Jerusalem that the doors of the Church were to be opened to the Gentiles; and in the account of that mission Silvanus and Judas are called leading men among the brethren ( Acts 15:22; Acts 15:27). Not only did he simply bear the message, he commended it in powerful words, for Silvanus was also a prophet ( Acts 15:32). During the first missionary journey Mark left Paul and Barnabas and returned home from Pamphylia ( Acts 13:13); in preparing for the second missionary journey Paul refused to have Mark with him again; the result was that Barnabas took Mark as his companion and Paul took Silvanus ( Acts 15:37-40). From that time forward Silvanus was for long Paul's right-hand man. He was with Paul in Philippi, where he was arrested and imprisoned with him ( Acts 16:19; Acts 16:25; Acts 16:29). He rejoined Paul in Corinth and with him preached the gospel there ( Acts 18:5; 2 Corinthians 1:19). So closely was he associated with Paul that in both the letters to the Thessalonians he is joined with Paul and Timothy as the senders of the letters( 1 Thessalonians 1:1; 2 Thessalonians 1:1). It is clear that Silvanus was a most notable man in the early church. As we saw in the introduction, it is most probable that Silvanus was far more than merely the scribe who wrote this letter for Peter and the bearer who delivered it. One of the difficulties of First Peter is the excellence of the Greek. It is Greek with such a classical tinge that it seems impossible that Peter the Galilaean fisherman should have written it for himself. Now Silvanus was not only a man of weight in the Church; he was also a Roman citizen ( Acts 16:37) and he would be much better educated than Peter was. Most probably he had a large share in the composition of this letter. We are told that in China, when a missionary wished to send a message to his people, he often wrote it in the best Chinese he could achieve, and then gave it to a Christian Chinese to correct and put into proper form; or, he might even just tell the Christian Chinese what he wished to say, leaving him to put it into literary form for his approval. That is most likely what Peter did. He either gave his letter to Silvanus to polish into excellent Greek or else he told Silvanus what he wished said and left him to say it, adding the last three verses as his personal greeting. Silvanus was one of those men the Church can never do without. He was content to take the second place and to serve almost in the background so long as God's work was done. It was enough for him that he was Paul's assistant, even if Paul for ever overshadowed him. It was enough for him to be Peter's penman, even if it meant only a bare mention of his name at the end of the letter. For all that, it is no little thing to go down in history as the faithful henchman on whom both Peter and Paul depended. The Church always has need of people like Silvanus and many who cannot be Peters or Pauls can still assist the Peters and Pauls to do their work.
