Remember what your mom always told you, "Honesty is the best policy?"
When we're young and impressionable, we are honest. Children are honest with their thoughts, words and actions. Children are emotionally and intellectually honest about their feelings and observations; sometimes to the point of embarrassment to their parents!
Honesty requires humility. Humility in itself can be self-embarrassing in that we have to show ourselves as we are. Humility requires a certain "nakedness" of thought and being. Children, in their innocence, are more humble and honest. Jesus calls attention to this fact when He says, "I tell you the truth, unless you change and become like little children, you will never enter the Kingdom of God. Therefore, whoever humbles himself like this child is the greatest in the Kingdom of Heaven." Matthew 18:3-4.
