I’m not a believer but I like the idea of wishing the presence of a god with others. It’s not so much a blessing as a wish for company. If God is with you, he’s with you for all of it. It’s like having a friend, perhaps, or a dog.
Given the moodiness of the Judeo-Christian God, it’s also a bit like having a volatile Santa Claus ever at your elbow – always determining whether you are naughty or nice. So it can be either a friend or a monitor, depending on your perception of God.
