St. Therese Lisieux's deathbed explanation of remaining a little child before God:
It is to recognize our nothingness, to expect everything from God as a little child expects everything from its father; it is to be disquieted about nothing, having no other occupation but to gather the flowers of love and sacrifice, and of offering them to God in order to please Him.
To be little is not attributing to oneself the virtues that one practices, believing oneself capable of anything, but to recognize that God places his treasure in the hands of His little child to be used when necessary; but it remains always God's treasure. Finally, it is not to become discouraged over one's faults, for children fall often, but they are too little to hurt themselves very much.
