He only can bless who has power; he only can bless who can create: God alone can bless.
God looks upon His creature and blesses him.
This liturgical mediation is taken from Romano Guardini's book, Sacred Signs.
He calls him by name: His almighty love turns towards the heart and life-centre of His creature, and from God’s hand flows the power which gives growth, which gives fertility, health, and goodness: “I will have regard to you, and make you to grow.”
Only God can bless: for a blessing is a decree on what is, and what acts; blessing is a word of power from the Lord of creation, it is a promise and a prophecy from the Lord of providence; blessing is good fortune.
