St John's Chapel, Luke 6:41-42.
Who likes being gossiped about? No one?
Now, who has gossiped about someone else? You get the point.
No one likes it being done to them, but we all do it. And if you haven't done it, you will. Don't feel bad though; welcome to the human race!
Jesus knew this about us. He likened it to missing the plank in your own eye while criticizing someone else for the matchstick in their eye. (I had a plank and a match held up at this point.) That is, we apply standards to others that we do not maintain ourselves, and are often oblivious to this blindness.
Why? Well, I suppose we feel better about ourselves when we do it. But it gives us a false sense of self and fractures community. There is a better way to strengthen our sense of self rather than criticizing others, and, at the same time, have the courage to face our own truth and do something about it. The key is finding our sense of self in God. This does not mean that we can't find our own sense of self, but just that we do not rely on ourselves alone, for then we will tend to reinforce our sense of self at the expense of others.To find our sense of self in God is to give ourselves a foundation that is solid in itself, not requiring us to pull others down to build ourselves up.
