'Little Child' in the Bible

So, He called to Him a little child and placed him in front of them,

and said, "Truly I tell you, you will never enter the kingdom of heaven unless you turn [your life around] and become like little children [i.e., having child-like humility].

Therefore, the person who will humble himself, as this little child, is the most important person in the kingdom of heaven.

And the person who welcomes one little child like this, in my name [i.e., because he belongs to me], welcomes me [also].

Then some little children were brought to Jesus so he could pray and place His hands on them [i.e., to bestow a blessing on them]. But His disciples spoke harshly to the people [for doing this].

But Jesus said, "Allow these little children to come to me and stop trying to prevent them. For the kingdom of heaven belongs to such [humble ones] as these." [See 18:4].
