Although many commentators separate 1 Thessalonians 2:13–16 from 1 Thessalonians 2:1–12, it is probably correct to see these two sections as being closely related. Verses 1–12 deal with Paul’s own conduct and ministry during his initial visit, and verses 13–16 deal with the Thessalonians’ response to that ministry. The content of verse 13 in particular has a strong connection to verses 1–12: note how the repeated idea of the gospel of God (vv. 2, 4, 8, 9) becomes the focus of the Thessalonians’ response to Paul’s ministry (v. 13).
1 For you yourselves know, brothers, that our coming to you was not in vain.
