No, non of these scriptures say "the scripture alone contains all that God has revealed for the salvation of man and fellowship with Him". Some of these verses describe important qualities and uses of the Holy Writ, but "scripture alone" they do not describe.

Nowhere does the scripture say that there is a revelation outside of scripture

Sure it does:

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. [...] 30 I will not now speak many things with you.

(John 14)

Note the future tense.

You can go even quieter: "Be still and know that I am God."

Note the future tense."

Yes and here is what Jesus was talking about. You really have to compare scripture with scripture to get the full picture, you can't just pull "proof texts" out of context that are explained in other scripture.

John 20: 30-31, "And many other signs truly did Jesus in the presence of his disciples, which are not written in this book: But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name."
