Honestly, sometimes the very best thing we can say or do in the presence of (usually unfounded) criticism is nothing. While I stumble at times, I have generally learned the importance of letting God defend me, even though suffering attacks on my reputation, ability, and character — all of which have been attacked at one point or another — is very painful business, indeed.
However, I have observed a remarkable correlation between the insensitivity of the person’s comment and a flat-out smallness of mind, and I refuse to engage with such wanton foolishness willingly (even the Bible concurs! Read the book of Proverbs). I’m not saying that a harsh critic is necessarily unintelligent, but rather that the person seems to be unwise, unwilling to listen, and primarily interested in promoting his/her own agenda.
So yes, I think Mr. Tozer was on to something with these words; after all, often the best thing we can say (or do) in the face of our critics is nothing at all! 💡
