Christ is one author and perfecter, or the finisher our new born again faith, called the Alfa and Omega. He as our confidence promises us (Philipian1:6 ) if he has begun his good work of salvation in us he will work it out to the end according to his unfailing labor oflove .
Yes one author of one cohesive book made up of many chapters called books.
For instance say that Revelation 22:18-19 applies only to the Book or chapter of Revelation.Would it apply only to the Book of Revelation? Let's add a chapter to the book of Revelation and call that also a part of the perfect Word of prophecy.
Now it would seem in effect we have added that chapter now to the whole Bible, because the Book of Revelation is an integral, cohesive part of the whole Bible. I would think anything added to the Book of Revelation is added to the Bible, the book of Prophecy.
It would be like saying, "Well I don't like Revelation 19 and 20. Let's take that out of the Book of Revelation. Then you would have taken it out of the Bible, because the Book of Revelation again is an integral cohesive part of the whole Word of God.
Whether a person wants to understand "the words of this book" of Revelation of 22:18 as meaning the Book or chapter of Revelation or being the whole Bible the perfect has come , it really makes no difference. Effectively it becomes the whole Bible
Why go above that which is written? 1Corinthians 13 informs us new prophecy will cease along with any new knowledge that could come with it.
It would seem the elect heed the warning told beforehand .(any claims of new revelations that can add believe not, (no faith )the perfect has come.
Matthew 24:23-25 King James Version Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.Behold, I have told you before.
Not believing the idea that God is still silent they will look to the great signs as wonders, the displays of the god of this world.
God living will is sealed up till the end of time . Why go above it?
