Should one be offended?
When I was younger, if a driver of a car cut in front of me or whatever, I would become angry/offended. I would admire other drivers who didn't become angry over the rudeness of other drivers.
These days, I barely give notice to rude drivers. I choose not to be offended.
In marriage, one needs to not become offended with your spouse, if the issue is not one of sin. Becoming offended over adultery is very acceptable. Of course, when one was under the Old Covenant, the adulterer or adulteress was stoned. A permanent solution to being offended!
As a Christian, one should say or do nothing to purposely cause an offense.
"It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak" Romans 14:21
"Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:" 1 Corinthians 10:32
In Jesus,
