"But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also." Matthew 5:39
A strange verse. Some people would interpret this as living a completely passive lifestyle, never defending oneself. From their viewpoint, this even forbids service in the military!
Chambers talks about when you are insulted, you must not only resent it, but must make it an opportunity to exhibit the Son of God in your life.
I think that means let the words and attacks go. They are just words. Internet comment blogs are full of people attacking each other from the safety of their own computers. Is this really accomplishing anything?
However when it comes to actually attacking oneself and family, then I believe we have a duty to respond and defend ourselves and family.
Words are just words, let them go. But actually attacks need to be dealt with.
