1 Thessalonians 2:2

But even after that we had suffered before,.... Before they came to Thessalonica, which they would not have done, had their ministry been a light and empty one in itself, and unprofitable to others; and especially had this been the case, they would never have rashly engaged in it again, and exposed themselves to fresh sufferings and dangers, as they did:and were shamefully entreated, as ye know, at Philippi; being beaten with many stripes, and put into prison, and their feet made fast in the stocks, at the instigation of the masters of the damsel that had a spirit of divination, by whom they got much gain, and which Paul dispossessed; see Ac 16:16we were bold in our God to speak unto you the Gospel of God with much contention: and which still made it more manifestly appear, that the errand they came upon was a matter of importance, and that they did not proceed on a slight foundation: what they spoke was "the Gospel", salvation by Christ, and not by the works of the law; the pure Gospel, and not a mixed one, free from the mixture of all human doctrines and inventions of men, without any adulteration and inconsistency; the whole of the Gospel, and not a part of it only; they declared the whole counsel of God, and kept back nothing that might be profitable: and this is styled the Gospel of God, to distinguish it from the Gospel of men, or that which the false teachers taught, and which was called the Gospel, though it was not so; and to express the excellency of it, from the author of it, who is God, it being the produce of his wisdom and grace; and from the matter of it, it containing the good will of God to men, setting forth the grace of God in election, redemption, justification, pardon, adoption, regeneration, and glorification, and expressing things relating to the kingdom of God, a meetness for it, and a right unto it; and it being so called shows it to be something divine, a message sent from God to sinful men; and gives a reason why the apostles were so bold to speak it, because it was not of men, but God.
