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.
The gospel is grounded in history and focuses on the death, burial, and resurrection of Jesus (1 Corinthians 15:3-4). There are several different designations for the gospel, but there is only one gospel (Galatians 1:6-9). "In its origin Paul’s gospel is of God (1 Thessalonians 2:2; 1 Thessalonians 2:8-9), in its substance it is Christ’s (3:2; 2 Thessalonians 1:8), and Paul is only the bearer of it (1 Thessalonians 2:4; 1 Thessalonians 2:9; 2 Thessalonians 2:14) as Milligan points out" (Robertson 10).
