I first heard the phrase ‘Get used to different’ from a friend while we were talking about interdenominational fellowship of Christians. Another friend asked me this question unexpectedly on a separate day. “What is the difference between Catholics and Christians?”
It can be hard to pick friends, especially good friends, but God will help you. A good friend can be caring or kind. Your friend does not have to believe in God, it can just be a friend you think is the right friend. But you can pray to God for your friend to know God.
