Catechism of the Catholic Church

Second, a humble and trusting heart that enables us "to turn and become like children": for it is to "little children" that the Father is revealed. (2562) > [The prayer is accomplished] by the contemplation of God alone, and by the warmth of love, through which the soul, molded and directed to love him, speaks very familiarly to God as to its own Father with special devotion. > Our Father: at this name love is aroused in us... and the confidence of obtaining what we are about to ask.... What would he not give to his children who ask, since he has already granted them the gift of being his children?
