We do get Truth from the Spirit of God as found in the Holy Bible.
I don't disagree with you. It is a great resource.
This is why the bible exists..... as the words in the Holy Bible are spirit and they are LIFE.
If a person decides to make a glass bottle, then fills it up with water from a lake, then the bottle was made to contain water. It is a water bottle.
If various people gather water from the same lake and puts that water into water bottles then put them together in a carton. You have a carton of water bottles.
Does that carton of water bottles contain all the water in the lake? Of course not.
Nor does a bible (carton), no matter if it contains 80, 73, 66 books. Even if it contained a million books it would not come close to holding every word that comes from the mouth of God, God's words.
Jesus said.>>"the words i have spoken to you, are spirit and life"..
Words of Jesus which John heard with his ears. Absolutely
So, where do you find those words of Jesus?
A.) IN The New Testament.
A very few of course. Hear what John concluded
Jhn 21:24 This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.
Why is it true?
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
(For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;)
That which we have seen and heard declare we unto you. 1Jn 1:1-3
Jhn 21:25 And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
