Therefore. — By this word, just as at the conclusion of the description of the “depth of the riches of the wisdom of God” (in Romans 11:33-36), or of the glorious climax of the doctrine of the resurrection (in 1 Corinthians 15:50-57), St. Paul makes the vision of future glory to be an inspiring force, giving life to the sober, practical duties of the present time. For the faith, which is the root of good works, is not only “the evidence of things not seen,” although already existing as spiritual realities, but also “the substantiation of things hoped for” (Hebrews 11:1).
Dearly beloved and longed for... — The peculiar affectionateness of this verse is notable. It is curiously coincident with the words addressed years before to Thessalonica (1 Thessalonians 2:19), “What is our hope and joy and crown of rejoicing? Are not ye in the presence of our Lord Jesus Christ...? Ye are our glory and our joy.” But it has just the addition natural to the yearnings of captivity: they are “longed for,” and that (see Philippians 1:8) “in the heart of Jesus Christ.” The “crown” is here the garland, the sign of victory in the apostolic race and struggle of which he had spoken above (Philippians 3:12-14). The crown of glory, of righteousness, and of life, is usually described as future (see 2 Timothy 4:8; James 1:12; 1 Peter 5:4; Revelation 2:10), and this is the case in the Thessalonian Epistle. Here, without excluding that completer sense, the reference is also to the present. The Philippians are St. Paul’s crown, as the Corinthians are his “seal” (1 Corinthians 9:2) — at once the proof of His apostolic mission and the reward of his apostolic labour. In both aspects the present is the earnest of the future.
