With men, where Jesus and the Bible itself comes from is a matter of faith, whether from heaven or from men.
I suppose many people think that way, however, there happens to be objective proof.
Isaiah 41:21-24 KJV
21) Produce your cause, saith the LORD; bring forth your strong reasons, saith the King of Jacob.
22)
Let them bring them forth, and shew us what shall happen: let them shew the former things, what they be, that we may consider them, and know the latter end of them; or declare us things for to come.
23)
Shew the things that are to come hereafter, that we may know that ye are gods: yea, do good, or do evil, that we may be dismayed, and behold it together.
24) Behold, ye are of nothing, and your work of nought: an abomination is he that chooseth you.
Isaiah 44:6-8 KJV
6) Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
7) And who, as I, shall call, and shall declare it, and set it in order for me, since I appointed the ancient people? and the things that are coming, and shall come, let them shew unto them.
8) Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
Isaiah 45:20-21 KJV
20) Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that set up the wood of their graven image, and pray unto a god that cannot save.
21) Tell ye, and bring them near; yea, let them take counsel together:
who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.
Isaiah 46:9-10 KJV
9) Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,
10)
Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
Only the true God can tell the end from the beginning. And that's what we find in the Bible, accurate foretelling of future events. This means that the Author is outside this time/space continuum. It's not just on faith, we have evidence. Proof.
Much love!
