@Macabeus , you have mentioned that you have been wronged by and insulted by others. Nobody really enjoys being wronged or insulted and neither would I.
Please consider these words from Ecclesiastes 7:21-22( NKJV ):
"Also do not take to heart everything people say,
Lest you hear your servant cursing you.
For many times, also, your own heart has known
That even you have cursed others. "
And also Proverbs 13:10( NKJV ):
"By pride comes nothing but strife, But with the well-advised
is wisdom."
I believe that often times in conflict and when people are saying unkind things back and forth, there is this element of pride in the mix. I find it to be the case with myself that when I have felt offended or insulted, often times I have spoken too quickly and said things or spoken in a way I later regretted.
