Someone does you a good deed, and if you are a believer you might say “thank you”, but some might respond by wrongly saying “you have blessed me”, or “that was such a blessing!” In fact, no man can bless... only God. When Isaac gave his blessing to his son Jacob he couldn’t take it back because he had conceded to Jacob his own favored status with God. Who do you bestow your blessing on, or do you understand how important that is?
