This, Jesus said to the tempter, the devil, when he told him to turn rocks into bread.
How can we live by what comes out of the mouth of God, if we do not know His voice?
Jesus said, in John 10:27-28 KJV, My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
This voice Jesus was talking about did not come from a man. This voice did not come from a book. This voice he was talking about came forth from the living God.
And again in John 10:5 KJV, And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
So how do we begin to know the voice of our heavenly Father? God, our father is talking, but is He talking to us? If He is, how do we learn to know His voice?
