What does childlike innocence mean?

Childlike innocence is the attitude of heart where one is untainted by pride, self importance and open to the good with a pure heart. Children are naturally pure, innocent and trusting, and these are characteristics of childlike innocence. Jesus Christ stated that, "... unless you become like little children you will not enter the kingdom of heaven" (Mt 18:3). So to be childlike is simply to be open and trusting, with no ill will or evil intentions.
