Many years ago, a friend of mine gave me a pair of basketball shoes that he said he took from the Lost & Found at his gym (they weren’t his). At the time, I wasn’t super into my faith, so it was never disturbing for me to use them, but now that I am, I don’t know if I should be. Is it (at all) sinful to keep using these basketball shoes? There’s no way the original owner could be found now.
What would you do? Give them away to charity? Keep using them?
