Matthew 18:3-5, 10, 14

And he said: “Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever takes the lowly position of this child is the greatest in the kingdom of heaven. And whoever welcomes one such child in my name welcomes me.

“See that you do not despise one of these little ones. For I tell you that their angels in heaven always see the face of my Father in heaven.

In the same way your Father in heaven is not willing that any of these little ones should perish.
