Public Displays of Affection. Why do people do it? Why do couple kiss and hug while riding on the escalator, while one step down is we common folk who come up close to the action? Is the only time that people are together when they are in public, in full view of everyone?
Are they trying to make us jealous? Are they exhibitionists? I mean, let's admit it. Some of things people do in the park, on the train, at the movies are pretty "PG-13", know what I mean?
I suppose one of the benefits of being in a relationship is just that. You have the right to rub it in everyone's face. PDAs are a boundary marker that sets people off and creates exclusivity from the rest of society. It says, "This person is MINE."
I think this is something that God does too. Remember Jesus' baptism when the heavens rented open and the Father said to the people, "This is my BELOVED SON." Remember when He rescued Israel out of Egypt with an OUT STRETCHED arm, a column of fire and cloud, so that all the nations could see and melt with fear as they saw how God favoured the children of Israel.
Perhaps there's something to be said about loving someone, and not only showing them privately, but publicly.
