Saint Louis de Montfort
But it is not enough to be just unafraid. God wants you to hope for great things from him and to be filled with joy by reason of this hope. Our bountiful Father wants to give you the kingdom of his grace. He has made you his kings and priests by the Christian faith and the priestly ordination he has conferred on you, and your voluntary poverty gives you an additional right to be called kings, for blessed are the poor in spirit for theirs is the kingdom of heaven (Matt. 5:3).
Our Lord does not merely promise the kingdom of heaven in the future but states that, because you are poor in spirit, you possess it now.
