In context of course Paul is speaking about comforting one another (like-minded believers) about the return of Christ 1 Thessalonians 4:14-18.
Yet is it not the “Christian” duty to comfort one another whenever possible? Not just here as Paul describes Christ’s return but in all things. Here are some of my favorite verses on the subject:
Romans 15:5 – Working to build up our neighbors
1 Thessalonians 5:11 – Building each other up through comfort and encouragement
Hebrews 10:23-25 – Encouraging one another to to love and to do good deeds
We all have busy lives, often too busy for those around us, but make an effort to see those in need, say a kind word and share the Love of Christ today.
