Luke 18:15-17

15 And they brought unto him also infants, that he might touch them. Which when the disciples saw, they rebuked them.

16 But Jesus, calling them together, said: Suffer children to come to me and forbid them not: for of such is the kingdom of God.

17 Amen, I say to you: Whosoever shall not receive the kingdom of God as a child shall not enter into it.
