Jesus, however, corrected the disciples and encouraged the parents to continue bringing their children to Him. Jesus had an interest in the children because they illustrated the humility necessary to enter the kingdom. Obviously infants are not humble in the same sense that adults show humility, but infants are humble in the sense of being totally dependent and unable to provide for themselves. They receive rather than provide, and in those qualities they are good examples of humility. Without this sense of being unable to provide for oneself and a willingness to receive from another no adult can enter the kingdom. [source][source][source]
Jesus also had an interest in these children for their own sake. As we have seen, one of Luke"s characteristic emphases in his Gospel was Jesus" interest in the needy, outcasts, and other types of dependent people ( Luke 4:18; et al.). [source][source][source]
