How can it be proved that there has been no "man made" corruption of the bible given the many documented, translations, interpretations, and "editings" of the text by subsequent emperors, kings, popes etc....
To answer your question NO you will never find proof of the veracity of any of God's word.
Your question could just as well ask is there proof that God is real, or that Jesus death paid for our sins, or for proof of any thesis in Christianity; and the answer would always be no.
That same question can be asked about a myriad of things concerning Christianity and the answer would still be no.
Christianity and faith are synonymous. A thing that is proven is no longer faith it then becomes knowledge.
The following Scriptures help to explain faith:
Romans 3:25 KJV
1st Corinthians 15:14 KJV
1st Corinthians 15:17 KJV
2nd Corinthians 4:18 KJV
The deeper question here is why does God not prove that the Bible is the word of God and that Jesus death on the cross paid our sin debt in full?
That question can be answered by many Scriptures here are three which I find applicable:
Hebrews 11:1 KJV
John 3:16 and 17 KJV
Back to the question of why God doesn't just prove all of this?
If there were proof then God would be taking away what we know as choice since those things would no longer be debatable, which in turn means that we would no longer have a free will.
If God wanted us to be automatons he would not have given us a choice to begin with. God does not just want our obedience; he wants us to obey out of love, and a desire to please him. Consider the following two Scriptures:
1st John 4:8 and 16 KJV
We cannot accept God but not accept his love, but many people accept his love but do not accept him.
