That would describe a blind faith.
"As if God does not supply good warrant (if not scientific certainty) for a step of faith, and as taken and confirmed, consequently more for the next one."
Amen to that.2 Peter 1 speaks directly to your point...
"Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ."
also...
"For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.And this voice which came from heaven we heard, when we were with him in the holy mount."
and yet more...
"We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts."
Here is a man who knows he is about to die and yet foremost in his mind is giving reason for faith.Giving reason to those who will follow.Telling those who diligently seek it that God will give it in abundance and that those who take it will never fall!
N.E.V.E.R. F.A.L.L.
Still...'faith'...sounds like a word churchy folks use,so there can't be any real evidence because,well,there just can't.
And which is not nebulous oral tradition that is made equal to Scripture and channeled into doctrine by a supreme authority in Rome, but he is referring to Scripture.
