In the home study group I attend, we discovered that I was the only one who has become a member of our church. Everyone else has attended this church for at least three years, but no one else has made a commitment to join it. Other than Hebrews 10:25 that commands us not to cease having fellowship together, are there any places in the Bible that call for joining a particular congregation?
Church membership is not a Biblical requirement. It’s a matter of personal choice. From God’s point of view, there is only one true Church and all who receive Jesus as their Lord and Savior are automatically part of it, regardless of where they decide to worship Him.
I love the answer that the head of one major organization gave to the question, “How do I join this church?” He said, “You can’t join it. You have to be born into it.” That’s the way the Lord intended it.
