The scriptures make it clear that pride is an abomination. Pride is one of the qualities specifically identified as sinful. Perhaps because pride makes us feel like God.
It's tempting to overlook the fact that the patient is doing the healing, not you. Sure, you found the ignition, inserted the key and turned it (adjustment), but what happens next is outside your control. You can take credit (if you dare) but the credit actually belongs to their Maker who installed the capability to self-heal in the first place!
The marketplace quickly ferrets out arrogant, conceited and prideful chiropractors who are revealed by their response to grateful patients:
"Oh, it was nothing." (Really?)
"We got lucky this time." (Lucky?)
"Tell your friends." (So I can help them, too.)
"You're welcome." (I deserve the credit.)
Pride. It can cause you to forget that you're merely an instrument. It's sooooooo tempting to take the credit!
