Strange that you ignore Scripture:
"[26] But the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you." [John 14:26]
"[30] Many other signs also did Jesus in the sight of his disciples, which are not written in this book." [John 20:30]
"[25] But there are also many other things which Jesus did; which, if they were written every one, the world itself, I think, would not be able to contain the books that should be written." [John 21:25]
I do not ignore a single verse.
That said, there is no verse that is a blank check, that can mean whatever you want it to mean.
By pretending that anything and everything is true, you obliterate the line between truth and falsehood.
Here's John 20:30-31, which includes the WHOLE sentence that John wrote, not just the first half.
John 20:30-31 Now Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
All the other stuff that jesus did that was not recorded was not necessary by John's own admission.
The stuff he wrote down was all that is needed to come to a saving knowledge of Jesus Christ.
For that matter, the Gospel of John provides enough information about the gospel to lead someone to salvation.
