Eliezer is sent by his master, Abraham, to find a wife for his son Isaac. He meets Rebecca who gives water to Eliezer and his caravan. When he finds out that Rebecca was Abraham’s grand-niece, Eliezer blesses G-d for having granted him success in his mission.
He said, “Blessed be G-d, G-d of my master Abraham,
who has not withheld His kindness and truth from
my master. G-d has guided me along the road to the
house of my master’s brothers.”
Genesis 24:27
We can easily understand how we can praise G-d or give thanks to Him. But how can we bless Him? What blessing can we mortal humans bestow upon Almighty G-d?
We can answer this question by noting that the verb “to bless” in Hebrew means “to bend down,” “to draw down” or “to extend.” By acknowledging G-d’s presence and involvement in our lives, we draw Him down into the world, so to speak. G-d created the world in such a way as to hide His presence, making it our mission to overcome this concealment. It is in this sense that we can “bless” G-d, enabling Him – through us – to be more revealed in the world than would be naturally possible.
Thus, reciting a blessing over good news, over food, or over the opportunity to fulfill some commandment is much more than thanking G-d. By acknowledging G-d’s presence in our lives, we draw down and expand Divine consciousness within the material world, thereby “blessing” G-d with ever greater manifestation throughout reality.
