He had one of the sharpest minds on campus, and one of the sharpest wardrobes (thanks to his wife, Hester). His work in Science and Theology went beyond the bounds of theological study, adding an openly spiritual element to a global, interdisciplinary dialogue. What made him a good mentor and outstanding teacher: he found life fascinating, in its many aspects. He made writing my dissertation much more interesting for his presence on my committee. More than any of these things, Wentzel was a friend.

I spent many hours in the van Huyssteen home, as a guest and as the campus bartender for special events at the seminary. The social grace and gracious spirit to be welcoming, respectful, and comfortable in both circumstances were signs of confidence and hospitality that eluded many others.

Wentzel was part of my life, not just part of my academic life. He and Hester toasted my engagement, celebrated the births of my sons, and made life wonderful with their presence at the dinner table. I am so grateful for his life, and for the blessing he brought into mine.
