If we were talking about planetary objects we might say gravity.
So what is the interpersonal equivalent to gravity?
Let’s approach the problem first by asking the opposite question.
What pushes or pulls people apart?
What makes us want to separate from someone else?
I think it’s Selfishness.
It’s the perfect repellent.
When someone is selfish they are obviously not interested in others except, perhaps, as these other might be used or manipulated. And when any of us gets the hint we are being used or manipulated, assuming we have reasonable self esteem, we look for the nearest exit, some way to punch out.
Now, having a pretty good insight on the opposite question, perhaps we can return to the first one with a bit more clarity.
What draws people together?
The easiest answer that comes to my mind is Love.
I’ve written on this topic many times but it is worth reviewing often. Love is not a feeling. It is a relational force that draws people to care for one another.
It’s invisible and powerful, sort of like gravity.
Be watchful,
stand firm in the faith,
act like men,
be strong.
Let all that you do be done in love.
