Look also at johns witness and it’s effect working with Jesus
“If I do not the works of my Father, believe me not. But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him.
And many resorted unto him, and said, John did no miracle: but all things that John spake of this man were true. And many believed on him there.”
John 10:37-38, 41-42 KJV
Bit remember which group we are in
“Neither pray I for these alone, ( the chosen apostles ) but for them also which shall believe on me through their word; ( the Bible’s nt ) that they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us:
that the world may believe that thou hast sent me.”
John 17:20-21
The Gospel was sent out from Jerusalem preached by the apostles to all nations so that the world could believe . There words make up the New Testament the four gospels are the apostles witness even Luke he took the account of the apostles and early church . All the epistles also the apostles of Jesus feneretion he blessed and annointed and sent forth spreading the gospel .
what I’m meaning is we aren’t the apostles but those who are meant to receive the apostles message of salvation commissioned by Jesus
“But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judæa, and in Samaria, and unto the uttermost part of the earth.”
Acts 1:8 KJV
everywhere the nt is oresched or written in a Bible tbier witness and words make it possible for the world to believe in Jesus the message of the gospel itself
