They do not doubt.
Their life is simple because they so easily believe. They believe in fairy tales and magic. They believe all the promises made to them without the urge to question. When they pray, they believe God will hear.
They ask boldly.
They are able to approach an adult and ask boldly without the fear of rejection. They do not procrastinate due to fear and worry. When they have a need, they will ask and be expectant.
They easily forget
They do not waste their life crying over broken toys or broken promises; they will cry a little but they will not dwell in their misery.
Little children’s simplicity cause continuous joy in their life. They are able to laugh whole heartedly and live their life to the fullest. When they ask, they believe they will receive.
We adult tend to complicate things with theories and hypotheses. Shouldn’t we slow down and let the little children teach us how to be more childlike when we approach God?
Matthew 18:3
And he said: "I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven.
