Webster says it is to return like for like.  
We all know the golden rule, ‘Do unto others as you would have them do unto you’. (Mt. 7:12)
Often, we choose to understand it as ‘Whatever others do to me, that’s what I can do to them’. 
 We want to justify our own desire to retaliate. 
Life gets difficult. Relationships get complicated. People are people…with sin natures. We live in a fallen world, with fallen people.  Some of them redeemed, some not. People don’t always do the right thing.
I don’t always do the right thing. 
But I am not given freedom to retaliate.  If we were, where would it end?  
It can end with me.  Right here. Right now. 
I continue to seek, to listen and  to hear, then follow the Holy Spirit that is within.  I am assured that He is there…“God has said, "Never will I leave you; never will I forsake you." (Heb. 13:5, Joshua 1:5)
“ Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires.”(Rom.8:5)
 I resolutely and repeatedly set my mind on Jesus, moment by moment choosing to believe His way and choosing to obey. 
Constantly, I am on the battlefield of flesh vs. spirit.
