We are saved by correct Gospel doctrine

Someone asked me to point them to the references that speak about the fact that we are saved by correct Gospel doctrine. They said, "I do remember that verse in the bible.... just can't remember the reference...."

Romans 10 says our Faith is Intellectual and Assent. If we believe with our hearts and confess with our mouths that Jesus is Lord then we will be saved.

Hebrews 11 shows us that our Faith is confessional and creedal. I simply believe in and believe that.

Matthew 7 shows us that we know a tree by its fruit. It just so happens that in this verse the fruit represents doctrine. It is the False prophets who are known for their false fruit. They speak on behalf of themselves.

John 15 demonstrates the fact that we must abide in Christ. We abide in Christ by Faith in him (which Romans 11 says is the fruit of the tree).

1 John 1 says that we heard the testimony of the Apostles. Our Faith is based upon the Prophets and the Apostles and not upon our own vain conceited ideas. 1 Corinthians 1-4 speaks of this fact in fact it speaks primarily of our epistemology. Through out the whole Bible we see references of certain people praying in the name of God, or God saying that it was by His name alone people were redeemed or rescued. The fact that God is a Person gives credence to the fact that we are saved to believe a certain standard. What we believe does matter.
