What is the root cause of hurt feelings?

This morning someone hurt my feelings :(

Context: Last week I noticed my co-worker didn't empty the coffee grounds out of his coffee maker in our office.  Being a "good guy" I decided to empty it out for him so that monday wouldn't bring a moldy surprise...(Things tend to mold twice as fast in Hawaii).

Fast forward: It's monday.  I greet him joyously, "Hey bro, Friday I emptied out your coffee grounds so it wouldn't be moldy today...

Let's just say I didn't get the response I wanted...

My feelings were hurt.  The first though was fleshly (i.e. from the enemy, the flesh), which was something like this: "Noted! buddy.  Next week I hope your coffee maker is full of mold." 

I know, I know, sooo not like the Savior.  I confessed that sinful thought and made it obedient to Christ :)

Herein lies the root cause of my hurt feelings: I DIDN'T EMPTY OUT THOSE OLD GROUNDS TO PLEASE THE FATHER!  I emptied out those old grounds to get a pat on the back!!  And when I didn't get my pat on the back, my feelings were hurt.  Had I acted solely to please the Father I would have been able to empty the coffee grounds and not seek out any recognition or validation the following monday.

And there you have it - the root cause of nearly every situation where feelings are hurt... because our motives are off.

Lord, thank you for your forgivness of my idolatry.  I place my joy solely in you.  I only seek your approval.  I choose to seek only your validation.  I choose to seek only your approval.  I choose to seek only you.  You are all I need.  Amen.

And I can't forget to forgive from the heart:  Lord, I choose to forgive.  I relinquish any desire in my heart to retaliate and any evil thought towards this person.  In fact, would you bless him...through me.  And heal my emotional bruise.  Thanks!

Blessings.
