I have said this before in other threads and I believe it. If by some catastrophic or man made by force event most if not all Bibles were destroyed The Word Of GOD continues to be taught to man. Man in his own follies thinks he or his church is why The Bible still exist today and that is simply not true. The Church of the believers in Christ is built upon the Rock of Divine Revelation and is proven time after time in scriptures. This was revealed when Christ told Peter that "No man has told you this but it was revealed to you by my Father in heaven." Divine Revelation through The Holy Spirit as promised believers by Christ is why the gates of hell can not prevail. That is how scripture can not go away. It is in our hearts. The Holy Spirit leads us into truth and warns us of wrong if we choose to listen that is.
In that respect this could not happen until Christ went to the cross and was risen. His last act was to given Them and the believers The Holy Spirit. This and this alone is what has kept The Gospel intact for 2000 years. If it were left up to man? We wouldn't recognize it. Added laws, added rules, added conditions, corruption, just like the scribes and Pharisees of old had done would make salvation through Jesus Christ a legalistic boondoggle no one could obtain or rather believe that they could. It would take reading decades of ancient text, understanding several languages, etc to understand what message Christ said in a few sentences if man had his way about it. A person should be able to to talk about & discuss salvation from remembered passages of the Four Gospels and help others.
Reading and relying on The Bible? Yes, reeading wise I rely on it alone as far as for sound doctorine, dogma, whatever term one wants to call it. But besides reading we should pray and listen more so for guidance from The Holy Spirit. I've read books discussing scriptures and even Hebrew traditions etc. But I rely on The Bible, The Holy Spirit, and prayer for the truth.
I am also reminded of Christ final ride into Jerusalem when the leaders of the Temple were telling Christ too rebuke or quieten the crowd.
Luke ch 19 38“Bless the King who comes in the name of the Lord! Peace in heaven and glory in highest heaven!”£ 39But some of the Pharisees among the crowd said, “Teacher, rebuke your followers for saying things like that!” 40He replied, “If they kept quiet, the stones along the road would burst into cheers!”
The rocks would burst into cheers. Clearly GOD's Word prevails despite mans deeds not because of mans doings.
