The answer is: His love and faith towards Jesus

v4-5

In the tiny letter to Philemon, we see Paul singing the praises of a man deeply rooted in his love for Jesus and for the people around him. Paul wasn't tuning into the usual gossip of the day; instead, he’d heard glowing reports of Philemon's genuine faith and warmth—traits that are like gems in a tough world.

Speaking of gems, did you know that Philemon was a leader in the Colossian church? This little nugget hints at his significant role in a formative Christian community even if we rarely think about him today. He was known not just for his belief but also for extending love that likely influenced others. This isn't just a one-off comment; it draws echoes of Jesus’ teachings about loving one's neighbor—not just when it's convenient but always.

It's fascinating to think that love and faith are lovingly intertwined, as Paul mentions love first and faith slightly afterward. It's that rich love which often fuels true faith, setting an inspiring foundation for others. Remember how 1 Corinthians 13 elevates love as the greatest virtue? It seems that long ago, Philemon was exemplifying this core message already!

Empires may come and go, historical figures may fade into obscurity, but a heart brimming with love and unwavering faith, as Philemon's evidently was, stands the test of time. No wonder Paul wanted everyone to know about him!
