Sandash, here's why nothing accidentally or deliberately done can prevent those that are sincere in their efforts to please God from learning the truth.
The Author and Originator of the Bible is also its Preserver. He is the One who caused this statement to be recorded:
“The word of our God endures forever.”—
Isaiah 40:8.
That statement is true, even though no original Bible manuscript of the Hebrew and Aramaic Scriptures
*or of the Christian Greek Scriptures has survived to our day. Therefore, how can we be so certain that the contents of the Bible we have today truly reflect the original inspired writings?
Those interested enough can read on.
