No man may come to God unless the Spirit of God draws them.

How will they know if they hear not the word?

Their rock is not our ROCK!

John 6:39-51 KJV

(40) And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
(41) The Jews then murmured at him, because he said, I am the bread which came down from heaven.

(43) Jesus therefore answered and said unto them, Murmur not among yourselves.
(44) No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
(45) It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
