My concern is with those who claim the Bible is the ONLY way to hear from God.
I think having a Bible in print has crippled us from hearing from God directly.
There may be more than one way to hear from God, but it should always be compared to what the Bible says, or else it opens the door to being led astray. Not every voice is from God. Both Muhammad and Joseph Smith claimed to get revelations from angels, but did they really? Even Satan can appear as an angel of light. For a Christian, the Bible should always be the standard on which all other revelations are weighed.
