Hebrews 8-10 made me think different and that the True church is one not made by human hands so that means everything else is counterfeit to the real thing. The true followers worship in Spirit and Truth and have no need for anyone to teach them anything God himself teaches us through the Holy Spirit. All that God requires is we live a life of Justice love and mercy towards others.
What has happened in the Christian world is that we follow what we see hence attaching ourselves to a denomination or organization.
Why do we keep looking for a physical representation of the Kingdom? It is already within us.
Luke 17: 20-21 (KJV)
20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
This is the Truth that many of us find hard to accept. This is the freedom that the Lord gave those who love him. The True church cannot be seen or touched it is "no part of the world" . Paul also spoke about the true church as one being not built by human hands and we can enter into with boldness and go right into the presence of Almighty God. This is spiritual and not physical.
