16But Jesus called them unto him, and said, Suffer little children to come unto me,
and forbid them not: for of such is the kingdom of God.
17 Verily I say unto you, Whosoever shall not receive the kingdom of God
as a little child shall in no wise enter therein.
my view on this verse is to come as a child means
your mind has to become like a blank slate, and forget what man taught you.
then you will be able to listen and learn the right way.
