This story is about a group of young believers in the hill country of Burma. They had the Bible, but no teachers except the Holy Spirit. They could only go by the New Testament and so they built their little church like the churches they read about in the Book.
Today there are thousands of Christians just recently saved. They have the Word of God but little else. They can meet together in houses and worship God as believers did in New Testament days. All of us would do well to get back to the Bible and follow God's pattern.
