Non-denominational Christianity is kind of like a big church with no specific name or label. It's like a group of friends who all believe in the same things about God and Jesus, but they don't belong to a particular church.
People who are non-denominational Christians often believe that it's important to focus on the teachings and life of Jesus, rather than specific man-made rules or traditions. They also believe in the importance of having a personal relationship with God, and that everyone can have this relationship no matter what background or beliefs they have.
Non-denominational Christians usually have their own pastors or leaders who teach them about God and lead their church services. They may also have their own set of beliefs and practices that are unique to their church, but they don't have to follow any specific rules set by a larger organization like some other churches do.
Overall, being a non-denominational Christian means a person has a strong faith in God and Jesus, but they choose to worship and practice their faith in a way that is unique to them and their church community.
