How can we be sure the Bible is true?
WTF?! Ok, I'll play.
Step 1. Do NOT read the Bible.
Step 2. Drop out of school.
Step 3. Do not become educated in anything Scientific.
Step 4. Do NOT develop critical thinking skills.
Step 5. Join a Christian religion and only listen to what the leaders of said religion tell you.
Edited to add: I have not yet watched the video. I usually have to work up to these things. Just my 2 cents worth on how to accomplish accepting the Bible as the inerrant word of God.
