The True Church -
Those who know and are taught by God and not by men -
The teachings of men lock people out of heaven -
Only God has keys that can open The Door.

Simon Peter answered, “You are the Messiah, the Son of the living God.”
Jesus replied, “You are blessed, Simon son of John, because my Father in heaven has revealed this to you. You did not learn this from any human being.
Now I say to you- that you are Peter, and upon this rock I will build my church, and all the powers of hell will not conquer it. And I will give you the keys of the Kingdom of Heaven. Whatever you forbid on earth will be forbidden in heaven, and whatever you permit on earth will be permitted in heaven.” Matthew 16:16-19

Same man wrong teacher -
But Peter took him aside and began to reprimand him for saying such things. “Heaven forbid, Lord,” he said. “This will never happen to you!”
Jesus turned to Peter and said, “Get away from me, Satan! You are a dangerous trap to me.
You are seeing things merely from a human point of view, not from God’s.” Matthew 16:22,23
