A 'house church' is like having your own little church at home with your family and friends. Instead of going to a big church building, people gather together in someone's house to worship and pray. It's like when you have a playdate with your friends at home, but instead of playing games, you talk about God and learn more about Jesus. Usually, a grown-up who knows a lot about the Bible becomes the leader of the house church, and they help everyone learn more about God. It's a cozy and comfortable way to worship, and you get to spend time with people you love while growing in your faith.
