Alan Knox regularly writes posts that are thoughtful, thought provoking, and soundly based on Kingdom principles/God’s Word. I love reading and commenting at his blog. He also has a collection of avid readers who add much with their comments. He recently wrote about the Church. What he wrote makes church simple. Church is all believers. Period. Yes, that is an “old” concept called the universal Church, but he demonstrates well how the scripture makes this clear, practically and conceptually.
