When someone does or says something to you its hard to try and keep from responding in the same tone in which they delivered their message to you? Someone pops off about something and you have to try and "bite your tongue" to keep from saying something to them.

Romans 12:17 - "Never pay back evil for evil to anyone. Respect what is right in the sight of all men."

It didn't say sometime.
It didn't say only on Mondays.
It said - Never pay back evil for evil.

We have to realize that once this day is over so are the things that have been done. Unless it was tragic, two and three years from now you may never remember what was said or done to cause you to want to retaliate. Also down the road, you may have opportunity to be a true witness to that person. Don't mess up today what God may have planned for you tomorrow.

You could be the person they are lashing out at today but next week you could be the person they are coming to for prayer. Just know that God has a plan for you to reach the lost so don't put yourself in a position where you can't be used.

Prayer: "God, please help us realize that you are bigger than any problem or situation we may encounter today. The enemy will use people to try and trip us up. But we know that we are the victors so we claim victory today."
