Well we certainly need whatever God provides. Since most, or even all of us on this forum, are blessed to have written Bibles, we should thank God for the blessing and make good and proper use of it. Not everyone is so blessed so we should especially hold those without up in prayer. If they are sincerely reaching out to them, will He ignore or neglect them because they do have access to a Bible? The key always is the heart of a person. With the right heart a person may be richly rewarded through the Bible, but as we read the blessings Jesus spoke to his audience in Matt 5:3-11 we should realize that those same blessings may be received by anyone. Owning a Bible again is not a prerequisite to receiving those blessings.
Simply having the Bible is Not a final assurance that we are OK with God. We also need to have a more personal connection with Him.
