In my remarks I was not advocating being a doormat, and the dire straights of the situation for "A" were unknown until Brenden's last post. I still stand by my previous post. There are occasions when certain actions to right a wrong are permissible and there are others when, for the sake of Christ, it is best to suffer loss and we do indeed need to turn the other cheek, as Paul pointed out:I used to think Jesus, in preaching to turn the other cheek, go the extra mile or give to the one who asks, was preaching a doormat righteousness, where we let people take advantage of us. But I realized one day that wasn't the case, he was merely addressing our own selfish internal attitudes that only consider how something effects us. If we are a doormat to people, we often hurt their character by reinforcing bad behavior, and thus being a doormat can be a self-centered thing, because you prefer not hurting someone over doing what would help them, and being passive over being active. It's like spoiling a child by lack of discipline or giving them everything they want, might seem like love, but it's only encouraging selfishness in both the parent (who feels good about it) and the child (who ends up without discipline or charity).
1 Corinthians 6:7 (NASB)
7. Actually, then, it is already a defeat for you, that you have lawsuits with one another. Why not rather be wronged? Why not rather be defrauded?
I am not saying that what Paul wrote exactly fits the case but there is a principle there that must be considered: What is best for Christ's sake should come first. And as I also pointed out, it may be wise to get a third party involved:
Galatians 6:1 (NASB)
6. Brethren, even if anyone is caught in any trespass, you who are spiritual, restore such a one in a spirit of gentleness; each one looking to yourself, so that you too will not be tempted.
The third party may or may not be appropriate as the first step; ideally "A" should discuss the problem with "B" first, but if "A" feels he might get angry or not have patience someone "who is spiritual" could be involved. We are dealing with a "babe" in Christ.
And I am not saying "A" is not spiritual.
