"Would you be happy for the rest of your life doing anything but teaching?"
I ask that question often to students who are seeking my counsel about going on for their doctorate to become a full-time professor of New Testament and Greek.
I've loved all 48 years that I've served the Lord as a teacher. It's like I was made for this. The 3 years I studied in Basel were the best years of my life. My profs believed in me. They set an example of what a great teacher looked like. I've never lived up to it. But it's been a great ride.
What has God created you to do and to be? When you find out what that is, pursue it with all your might.
