1 Thessalonians 2:17–20 (ESV)

17 But since we were torn away from you, brothers, for a short time, in person not in heart, we endeavored the more eagerly and with great desire to see you face to face,

Paul begins by assuring the Thessalonians that he not only longed for them but actually made a concerted effort to see them (1 Thessalonians 2:17). This effort was motivated by a desire to see them but was thwarted by Satan (1 Thessalonians 2:18). The desire in turn was inspired by a view of the coming of Christ, when the transformed lives of the Thessalonians would be a source of joy and honour for Paul (1 Thessalonians 2:19–20).
