Luke 18:15-17 NKJV

15 Then they also brought infants to Him that He might touch them; but when the disciples saw it, they rebuked them.
16 But Jesus called them to Him and said, "Let the little children come to Me, and do not forbid them; for of such is the kingdom of God.
17 Assuredly, I say to you, whoever does not receive the kingdom of God as a little child will by no means enter it."
