(Pro 18:19 KJV) A brother offended is harder to be won than a strong city: and their contentions are like the bars of a castle.
It might be important that this word “offended” (6586) is not a matter of getting your nose in a snit but of actually being sinned against. It would also seem that the sin was not an accident or mistake but a deliberate action. It has the meaning of rebelling.
How many times do we take established relationships and manipulate them. It could be as simple as taking something for granted, of not being grateful. It could be cold blooded destruction for personal gain. Once you tear down those connections that have been built over the years it is hard to reestablish them.
So? Whom do we take for granted. Here it mentions a “brother” (251). It might be a spouse or a parent. Something to think about for the day. I wonder how many people I will interact with and not stop to think about.
