and that our Gospel came to you not in word only, but also in power, and in the Holy Spirit, and with much assurance. You know what kind of men we showed ourselves to be among you for your sake.
But there is more to the gospel than just words. Vincent says, "The gospel did not appeal to them as mere eloquent and learned discourse" (Vol. IV ). That is why the apostle introduces the notion of power in connection with the gospel. It is unlikely that the word "power" refers to miracles. As Hogg and Vine point out, "no miracles are recorded in connection with the preaching of the gospel at Thessalonica" (35). It is more likely that Paul is emphasizing that the gospel came as a vital force, resulting in an election that consisted of obedience to that gospel. Their election consists of their obedience to that gospel. The gospel is not just an announcement of a plan of salvation but the application of the "power of God unto salvation" (Romans 1:16). In commenting on the words "in power," Vincent says, "Power of spiritual persuasion and conviction: not power as displayed in miracles, at least not principally, although miraculous demonstrations may be included" (Vol. IV 17).
