In modern usage, a blessing is thought of as a prayer, as in saying a blessing before a meal.
In the Bible and in religious contexts, a blessing, or to bless someone, takes on greater significance. Blessing someone is wishing, bestowing, bequeathing, or praying for good will, prosperity, or God’s mercy. A blessing is given to a lesser person by a greater person (Hebrews 7:7).
A secondary definition of bless is “to honor as holy” or “to glorify.” In this respect we can “bless God” or “bless the Lord.” Not all translations of the Bible use this phrasing; in this context, often praise or exalt are used instead of bless
For additional insight, consider that the opposite of bless is curse.
When Abram went to the land God promised him, he took Lot with him even though he wasn’t supposed to. Abram had to deal with the consequences of his decision.
For Lot, there were consequences too. When he traveled with Abram, Lot prospered; he was a blessed man. However, once they separated, things turned bad for Lot. Without his uncle’s influence, Lot made some poor choices, eventually holed up in a cave he was fearful, broke, and alone – except for his two daughters, but that’s another story.
Sometimes things may go good for us just because of who we hang out with. But once we leave their umbrella of favor our positive outcomes can evaporate.
That’s why the company we keep is so important.
[Genesis 19:16-17, 30]
