Bless our home and make it fit for you, O God. Send your Holy Spirit into each nook and cranny. Let these walls resound with love and laughter. A Blessing attaches value to the one being blessed. We can't leave a blessing the same way you entered it.
Blessing is a ritual of a deep relationship.
The emphasis is not that you have the power to give a blessing, but that you care about the person being blessed. Bless your children, spouse, and relatives at times that are significant to them. We blessed Tom when he left on his trip to study in Africa. We blessed Marie's first car. The Lord look upon you kindly and give you peace.
