"And the angel called the two of them privately and said to them: "Praise God and give thanks to him; exalt him and give thanks to him in the presence of all the living for what he has done for you. It is good to praise God and to exalt his name, worthily declaring the works of God. Do not be slow to give him thanks."
Tobit 12: 6
"Gratitude, being nearly the greatest of human duties, is also nearly the most difficult."
"If ever you have felt, in the contemplation of a sunset or any perfect
work of nature or art... in the thrill of good news or in the passion of
first love, that it was really worthwhile being alive - then that
moment was a revelation to you, if you had the heart to understand, of
what you owe the Almighty for having created you."
Fr. Ronald Knox
