Remember where St. Paul talks about the fact that we’re all members of the same body, and that one part can’t say to another “I don’t need you”? Just because we don’t always recognize our place doesn’t mean we don’t have one, one that can’t be filled by anyone else. And a cross isn’t something we just have to live and suffer with, it’s something that ultimately will bring us closer to Christ. Perhaps not in a way that’s always comfortable.
Maybe think about your strengths and your virtues, your talents. Ask the Lord how you can use those for His work.
