So really--have you ever felt like smacking someone? Don't worry, I won't judge.
I've felt that way plenty of times in the past. Correction--my flesh (also known as the soul: my mind, my will, and my emotions) wanted to "reach out and touch someone" in a non-loving fashion. The wonderful thing is, it isn't a sin to have a rush of emotion well up inside. The sin comes when we act upon the anger and irritation.
Thank God I am not just made up of my brain; I have a spirit and a body (1 Thessalonians 5:23, Hebrews 4:12). Choosing to listen to the Holy Spirit and forgive instead of spewing out my displeasure isn't always easy--but it's end is so much better!
Please understand that this is different than "stuffing" emotions. When we stuff things instead of letting them out, we end up boiling over at some point...and it's never pretty. Forgiving someone is God's way of dealing with the feelings we have that doesn't cause harm to others--it actually benefits them.
Forgiving doesn't mean we'll never have to talk about issues or problems with others, but we do need to forgive them first, so we can approach it from the standpoint of the love of God.
With that said--enjoy your strife-free weekend!
Hatred stirs up strife, but love covers all sins. Proverbs 10:12
