Mathew :18:1-4, Be like Child to enter into the kingdom of heaven

Jesus said to disciples that unless you be like Child can't enter into the kingdom of heaven, one who does take low position is the greatest in the kingdom of heaven, if anyone wants to be great he must be Sarvent to all , Jesus came down to the Earth as a form human being and emptied himself and lived like a Sarventhood life, washed his disciples feet, we have to deny ourselves and walk with God as a Sarventhood life
