little and great faith, a new avenue?

How great a faith does it take to move mountains? Don't see how we can know until we are in the foxhole. This most vital of all subjects has held my attention before. It is the only way to please God. But I must do more than just confess I have faith. It is more than mere agreement with the pastor. How much faith does it take to be healed? The Bible only tells us one way, I think, and that is to read and reread in order to pack it down into our spirit. Not sure this is an entirely new way, but I have found listening to the Bible read is dramatically effective for me. The disc player I use can repeat one chapter as often as I want, enough to memorize it. I prefer the Alexander Scourby undramtized KJV. Some new translations shrink the meaning from the KJV. I am not qualified to discuss translaations but I notice simple things like the KJV will find Jesus saying let us go hence while a new politically correct one says let us leave. Also, a manchild is born becomes a baby is born. I wonder if this is just sprucing up to what we now find such shrinking meanings acceptable?
