In his Angelus address this past Sunday, Pope Benedict said:
He who welcomes the Lord in his life and loves him with all of his heart can begin again. He is able to do God’s will: to realize a new form of existence animated by love and destined for eternity.
When I go to Mass, I often recall a particular teaching of Pope John Paul II on Holy Communion, and the newness of life that it brings to us:
22. Incorporation into Christ, which is brought about by Baptism, is constantly renewed and consolidated by sharing in the Eucharistic Sacrifice, especially by that full sharing which takes place in sacramental communion.
Because of how frequently and repetitively I fail, this concept of “newness” is a source of great consolation to me. It motivates me to avoid dwelling despairingly on the past (after appropriate repentance, of course), but to look forward with hope to new opportunities to be faithful to the will of God. Such newness is possible only because of the mercy of our loving Lord. Such hope comes from having faith in that mercy, as we hear in Lamentations 3:21-23
But I will call this to mind, as my reason to have hope: The favors of the LORD are not exhausted, his mercies are not spent; They are renewed each morning, so great is his faithfulness.
