SEV Biblia, Chapter 18:17
De cierto os digo, que cualquiera que no recibiere el Reino de Dios como un niño, no entrará en él.
John Gill's Bible Commentary
Ver. 17. Verily I say unto you , etc.], Christ takes an occasion from hence to teach his disciples humility, and guard them against pride and vanity: whosoever shall not receive the kingdom of God ; the King Messiah, the doctrines of the Gospel, and the ordinances of it, even the whole Gospel dispensation; as a little child ; without prejudice, pride, ambition, and vanity, with meekness, and humility: shall in no wise enter therein ; a very unfit and improper person to be a professor of the Gospel; or to be admitted to Gospel ordinances: or be a member of a Gospel church; or be reckoned a subject of the Messiah's kingdom, which is of a spiritual nature; and as he has not a meetness for, and a right unto the kingdom of glory, he shall never see it, and enjoy it.
Matthew Henry Commentary
Verses 15-17 - None are too little, too young, to be brought to Christ, who knows ho to show kindness to those not capable of doing service to him. It is the mind of Christ, that little children should be brought to him. The promise is to us, and to our seed; therefore He will bid them welcom to him with us. And we must receive his kingdom as children, not be purchase, and must call it our Father's gift.

Robertson's NT Word Studies
18:17 {As a little child} (hws paidion). Jesus makes the child the model for those who seek entrance into the kingdom of God, not the adult the model for the child. He does not say that the child is already in the kingdom without coming to him. Jesus has made the child's world by understanding the child and opening the door for him.
