Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; Blessed be God - Let God have universal and eternal praise:
1. Because he is the Father of our Lord Jesus Christ, who is the gift of his endless love to man, John 1:16.
2. Because he is the Father of mercies, ὁ Πατηρ των οικτιρμων, the source whence all mercy flows, whether it respect the body or the soul, time or eternity; the source of tender mercy; for so the word implies. See on Romans 12:1 (note). And,
3. Because he is the God of all comfort - the Fountain whence all consolation, happiness, and bliss flow to angels and to men.
