Matthew 18:3-5, 10, 14

and said, Verily I say unto you, Except ye turn, and become as little children, ye shall in no wise enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is the greatest in the kingdom of heaven. And whoso shall receive one such little child in my name receiveth me

See that ye despise not one of these little ones: for I say unto you, that in heaven their angels do always behold the face of my Father who is in heaven.

Even so it is not the will of your Father who is in heaven, that one of these little ones should perish.
