Mark 10:13-16

And they were bringing children to him that he might touch them, and the disciples rebuked them. But when Jesus saw it he was indignant and said to them, “Let the children come to me; do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.” And he took them in his arms and blessed them, laying his hands on them.

There were people who thought that the Messiah should not keep company with common men. Even the disciples thought that Yeshu should not be bothered by little children.

But the children just saw his love, and Yeshu said that those with a childlike response to his goodness were the ones who would be admitted to his Paradise.
