In this introduction we have,
I. The inscription, where we have, 1. The persons from whom this epistle came, or by whom it was written. Paul was the inspired apostle and writer of this epistle, though he makes no mention of his apostleship, which was not doubted of by the Thessalonians, nor opposed by any false apostle among them. He joins Silvanus (or Silas) and Timotheus with himself (who had now come to him with an account of the prosperity of the churches in Macedonia), which shows this great apostle's humility, and how desirous he was to put honour upon the ministers of Christ who were of an inferior rank and standing. A good example this is to such ministers as are of greater abilities and reputation in the church than some others. 2. The persons to whom this epistle is written, namely, the church of the Thessalonians, the converted Jews and Gentiles in Thessalonica; and it is observable that this church is said to be in God the Father and in the Lord Jesus Christ; they had fellowship with the Father, and his Son Jesus Christ, 1 John 1:3. They were a Christian church, because they believed in God the Father and in the Lord Jesus Christ. They believed the principles both of natural and revealed religion. The Gentiles among them were turned to God from idols, and the Jews among them believed Jesus to be the promised Messias. All of them were devoted and dedicated to God the Father and the Lord Jesus Christ: to God as their chief good and highest end, to Jesus Christ as their Lord and Mediator between God and man. God the Father is the original centre of all natural religion; and Jesus Christ is the author and centre of all revealed religion. You believe in God, says our Saviour, believe also in me. John 14:1.
II. The salutation or apostolical benediction: Grace be with you, and peace from God our Father and the Lord Jesus Christ. This is the same for substance as in the other epistles. Grace and peace are well joined together; for the free grace or favour of God is the spring or fountain of all the peace and prosperity we do or can enjoy; and where there are gracious dispositions in us we may hope for peaceful thoughts in our own breasts; both grace and peace, and all spiritual blessings, come to us from God the Father and the Lord Jesus Christ; from God the original of all good, and from the Lord Jesus the purchaser of all good for us; from God in Christ, and so our Father in covenant, because he is the God and Father of our Lord Jesus Christ. Note, As all good comes from God, so no good can be hoped for by sinners but from God in Christ. And the best good may be expected from God as our Father for the sake of Christ
