It’s one thing to give out excellent advice, but quite another to put it into practice personally. He who busies himself with the sins of others, or judges his brother on suspicion, has not yet even begun to repent or to examine himself so as to discover his own sins.
So never condemn anyone. Greet everyone with a good disposition, whoever he may be, with the hope of finding in him only good, seeing before you the image of God.
It is obvious that in order to advance, we must have a closer look at ourselves.
