So hard to break indeed! It definitely requires discipline to make time with non-Christians for the sake of the kingdom. I have to watch myself because I’m pretty introverted and can be way too protective of my days off. Something that has helped me is to think about tithing my time, which is a gift in the first place, and spending it forming relationships with other people who don’t know Christ yet – but one day might!
Also, I think it’s great that you have the heart to expand your Christian bubble! I’ve found it happens slowly, but if you pray for new people, God answers – although sometimes (speaking from experience here…) it might require you to stretch yourself a little too. Such is my experience! Always nervous about talking to new people, I once invited a girl to a small group by saying, in one breath, “Hi! Um, do you like to go to church, because I have some girls over at my apartment that eat snacks on Tuesday night and we talk about the Bible and you should come if you happen to be free maybe but no pressure, really no pressure at all ok bye!” God didn’t need eloquence – just obedience. Surprising me (but not God!), she turned up, an answer to my prayer. So definitely pray for new people to invite to your Christian bubble, but also be willing to do what he wants you to do to get there!
One final thought…
I’m also thinking that maybe instead of inviting people into our Christian bubble, we could also try to join them in theirs. Indeed, a passion for golf or music or physical fitness can be just as God-given and holy as a calling to preach. If you find a group of people who need Him, but with whom you share a common interest, relationships emerge that can lead to those God-given, holy, and exciting conversations! And sometimes, you’ll find a believer there who, in between swings, songs, or reps, is doing the very same thing that you are
