Poor in spirit like children, the kingdom of heaven belongs to such as these (Matt 5:3, 19:14)

Matthew 5:3
“ Blessed are the poor in spirit, for theirs is the kingdom of heaven.

Then some children were brought to Him so that He might lay His hands on them and pray; and the disciples rebuked them. But Jesus said, “Let the children alone, and do not hinder them from coming to Me; for the kingdom of heaven belongs to such as these.” After laying His hands on them, He departed from there. Matt 19:13-15 NASB
