Is reading the Bible necessary for everyone? Is this question even important?
First, yes this question is important. Here's why: only in the 66 books of Holy Scripture is God's perfect will and purposes revealed to human kind concerning our relationship to Him. This may sound bold, or even radical, but it is the testimony of Scripture itself. When people tell me they can believe in Jesus without accepting the Bible as the authoritative Word of God, I ask them, "And how is it that you came to know what you do about Jesus, if it was not passed down through people who read the Bible?"
Now to answer the first question, I don't want to say that all people must be able to read and possess a translated copy of the Bible if they will be saved. But rather, what I will say is that the information the Bible communicates to us, as creatures made by God in His own image, is absolutely essential for us to be saved. Note the word "message". It is not the physical Bible, or the ability to read that is necessary, but the message contained in the Scriptures that all people must know to be saved.
Do you read it or listen to it? Do you tell it to others?
The fact that we have this communication given to us from our Maker and God is absolutely wonderful. Something we ought to give heartfelt thanks to the Savior for over and over again.
Grace to all in Christ Jesus our Lord!
