If you’re going to pray for or send good thoughts about world events, please don’t use hashtags.

Ironically, this is (kind of) covered in the bible:

And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by others. Truly I tell you, they have received their reward in full. But when you pray, go into your room, close the door and pray to your Father, who is unseen.
