During my time at Mid-America Bible College (now Mid-America Christian University) I wrote a small article for the January 1991 edition of the Reformation Witness. I was surprised (read: "shocked") when Dr. Max R. Gaulke, the founder of my alma mater, wrote me an encouraging note after he read my article.
I still have the note; here is a scan of it. Click on the note to expand the letter:
The Scriptural reference Gaulke included is as follows...
Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ. (Colossians 3:23-24 ESV)
