From Magnificat Monday, from the late Scripture scholar Father Ignace de la Potterie, S.J.:
Baptism and faith, introduces us to a new dynamic of being, sets a new dynamism within our lives. This treasure, recognized and embraced in the faith, makes all of life a journeying, a progressing, always preceded and accompanied by those same facts of grace worked by the Lord that come back and take our hearts by surprise, thus nourishing faith …. Man does not become son of God in any automatic way, by the law of nature, but by faith. The faith is the power given to become sons of God: … The same Presence that stirred faith in the first ones to be chosen continues to work in the here and now so that it amazes and still awakens faith today in the hearts of the men given to him by the Father.
The wind blows where it wills, and you can hear the sound it makes, but you do not know where it comes from or where it goes; so it is with everyone who is born of the Spirit.
