From a homily by Saint John Chrysostom, bishop, via the Liturgy of the Hours for Jan 26 (Memorial of Saints Timothy and Titus):
But, you may say: “Because of Christ, Paul found all this pleasant.” I cannot deny that, for he derived intense pleasure from what saddens us. I need not think only of perils and hardships. It was true even of the intense sorrow that made him cry out: Who is weak that I do not share the weakness? Who is scandalised that I am not consumed with indignation?
I urge you not simply to admire but also to imitate this splendid example of virtue, for, if we do, we can share his crown as well.
Are you surprised at my saying that if you have Paul’s merits, you will share that same reward? Then listen to Paul himself: I have fought the good fight, I have run the race, I have kept the faith. Henceforth a crown of justice awaits me, and the Lord, who is a just judge, will give it to me on that day – and not to me alone, but to those who desire his coming. You see how he calls all to share the same glory?
Now, since the same crown of glory is offered to all, let us eagerly strive to become worthy of these promised blessings.
