In 1 Thessalonians 3, Paul tells the Thessalonians that he could no longer bear to fear about their faith, so he sent Timothy to be with them because he was unable to come.
For this reason, when I could bear it no longer, I sent to learn about your faith, for fear that somehow the tempter had tempted you and our labor would be in vain. 1 Thessalonians 3:5 ESV
Paul knew the Thessalonians were young and weak in their faith. His concern for them mirrors a father’s concern for his child. Paul sent Timothy to exhort them in their faith, just as Solomon exhorts his son in Proverbs.
Be wise, my son, and make my heart glad, that I may answer him who reproaches me. Proverbs 27:11 ESV
Timothy returned to Paul with good news, the Thessalonians had stayed strong in their faith. Their steady faith and love comforted Paul during times of affliction and in his letter he tells them he prays for the day he came see them face to face. Paul also exhorts their faith, similarly to how Solomon exhorts those who follow God.
Blessed is the one who fears the LORD always, but whoever hardens his heart will fall into calamity. Whoever walks in integrity will be delivered, but he who is crooked in his ways will suddenly fall. Proverbs 28:14, 18 ESV
In his exhortation, Paul asks the LORD to increase the Thessalonians love for those around them. The Bible emphasizes on many occasions that Christians are called to love those around them, whether it be family, friends, or even complete strangers.
Now may our God and Father himself, and our Lord Jesus, direct our way to you, and may the Lord make you increase and abound in love for one another and for all, as we do for you, so that he may establish your hearts blames in holiness before our God and Father, at the coming of our Lord Jesus with all his saints. 1 Thessalonians 3:11-13 ESV
Dear God, please increase my love for those around me. Please help me show others Your love and strengthen my faith. In Your Holy Name, Amen.
