today's other readings are Psalm 98 and John 16: 16-20
You win some, you lose some.
That was a saying I first heard a long time ago. I think I first heard it when it came to playing one of the many sports I dabbled in when I was younger. In any case, the truth was apparent - whether it was an individual sport or a team sport, you weren't going to win every game. So be happy and proud when you or your team wins, and put your head down and try harder if you lost. One thing for sure. The losses helped me to appreciate the wins even more.
St. Paul's ministry was like that. In today's reading, and for that matter, yesterday's, (Acts 17: 22 - 18:1), are a reminder that when he was evangelizing, Paul had some wins, but he also had many losses. We hear of how the Jewish people in Corinth scoff at his preaching, so now he tries the Gentiles, with some success.
In our own efforts to evangelize, to live and share the faith with others, some may be inspired, and some may look on our efforts with apathy or even disdain. But we keep trying, fighting the good fight, living the good life. Just like St. Paul did.
