Mary is more blessed because she embraces faith in Christ than because she conceives the flesh of Christ said St. Augustine  

Our mother is a model of correspondence to grace. If we contemplate her life, our Lord will give us the light we need to divinize our everyday existence… . First, let us imitate her love. Charity cannot be content with just nice feelings; it must find its way into our conversations and, above all, into our deeds. The Virgin did not merely pronounce her fiat; in every moment she fulfilled that firm and irrevocable decision. So should we — Saint Josemaria Escriva.
