In Paul's opening, he greets Timothy and tells him that he remembers, prays, and longs to see him. He remembers his own ancestors and reminds Timothy about the faith of his own mother and grandmother. Ultimately, Paul is identifying with Timothy and stirring up in him a godly affection. They have both received the faith of those who came before them, and they both long for one another with tears and joy. Paul, who is now alone, knows like no other how valuable to the godly affection of Jesus' people for one another is. He is about to call Timothy to come share in suffering; he wants to first remind him how much they already share in the love of Christ and the affection of his Bride. Let us also consider how to stir one another up to love and affection. Let us cultivate a dear desire for one another!
