A Story from Elder Cleopa, Sihăstria Monastery, Romania

A man comes into the Church with demons riding him like a horse. The observer prays-"I am a sinful man, grant me mercy!"
At the end of the the service the man comes out freed from captivity.
Take on the sin of your brother. Pray for ourselves in the way we see another's need.
