Luke 18:16
But Jesus called His disciples to Him and said, "Allow these little children to come to me and stop trying to prevent them, for the kingdom of God belongs to such as these [i.e., humble ones. See Matt. 19:14].
Matthew 18:3-4

Acts 2:39

Otherwise, your children would be [considered] unclean. [Note: "Unclean" suggests they would be viewed as pagans were it not for one parent being a Christian]. But, as it is, they are set apart as acceptable [i.e., to God, because of the influence of the one Christian parent].
