Knowing this first, that no prophecy of the scripture is of any private interpretation. 
For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Spirit. 

II Peter 1: 21 & 22

“Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed. 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”.
(John 20: 29 – 31)
