ok, you rely on PEOPLE. I will contend you should rely on GOD.
People are fallible. God is not.
Faith is only as good as the object in which it is placed.
Faith in a Man or Woman, or Religion, or Building, or Good Works, or Charity, or Love does not save.
Only Faith in God saves. The old testament saints were saved by faith in God. They looked forward to the coming of his Messiah. The New Testament Saints and the Apostles placed their faith in God, through Jesus Christ the Messiah - God Incarnate.
The other apostles did not fall at the feet of Peter. They contended amongst themselves for the faith. Most of them died for it.
Here is an interestgin question. Imagine yourself having died and appearing at the gates of Heaven. Jesus asks - Why should you be allowed in my Heaven? What is your answer?
Did not in the scriptures, in Hebrews speak about the need to be with other believers as well? That is why we have Christian church communities.
