I love this quote from J.D. Grear:
“Getting doctrine right is a matter of life and death, but holding that doctrine in the right spirit is essential too. A great deal of damage is done by those who hold the truth of Christ with the spirit of Satan."
This is from the forward of the book "Humble Orthodoxy" by Josh Harris. I love that title and have used that phrase many, many times. I'm not sure of a more powerful two-word phrase. Sadly, it is powerful because (in my experience) it is often uncommon.
