Andreas Kostenberger has a nice section about humility in his book Excellence. He notes that humility is one of the “cardinal virtues in the Christian life and in academic work.” In the chapter Kostenberger quotes Calvin:
I was always exceedingly delighted with that saying of Chrysostom, “The foundation of our philosophy is humility”; and yet more pleased with that of Augustine: “As the orator, when asked, What is the first precept in eloquence? answered, Delivery: What is the second? Delivery: What is the third? Delivery: so if you ask me concerning the precepts of the Christian religion, I will answer, first, second, and third, Humility.”
Kostenberger also spends some time saying that we should be humble in our academics and ministry because 1) we could be wrong, 2) we are not nearly as brilliant as scholars before us, 3) our ministry is at most a mere footnote in history that will barely be mentioned by others in the future, and 4) in the overall scheme of things we are not that important. Our life is a vapor (James 4:14). Kostenberger then talked about celebrity pastors and near the end of this section on humility he noted a great quote by Luther:
[If] you feel and are inclined to think you have made it, flattering yourself with your own little books, teaching, or writing, because you have done it beautifully and preached excellently; if you are highly pleased when someone praises you in the presence of others; if you perhaps look for praise, and would sulk or quit what you are doing if you did not get it– if you are of that stripe, dear friend, then take yourself by the ears, and if you do this in the right way you will find a beautiful pair of big, long, shaggy donkey ears.
Then do not spare any expense! Decorate them with golden bells, so that people will be able to hear you wherever you go, point their fingers at you, and say, ‘See, see! There goes that clever beast, who can write such exquisite books and preach so remarkably well.’ That very moment you will be blessed and blessed beyond measure in the kingdom of heaven. Yes, in that heaven where hellfire is ready for the devil and his angels. To sum up: Let us be proud and seek honor in the places where we can. But in this Book the honor is God’s alone, as it is said, ‘God opposes the proud, but gives grace to the humble’ (1 Pet. 5:5); to whom be glory, world without end, Amen.
The above quotes came from chapter 15 of Excellence: The Character of God and the Pursuit of Scholarly Virtue by Andreas Kostenberger.
