Engineering Through the Lens of Faith

From the Authors:

The following book grew out of a series of classroom devotionals presented at LeTourneau University, coupled with various workshop and seminar presentations and conference papers.

Volume One deals with foundations: faith, truth, vocation, science, mathematics.
Volume Two deals with applications: ethics, technology, workplace, and missions.

It is the sincere hope of the authors that this book will strengthen your walk with Jesus and help you to connect your faith with your vocation.

Dr. Paul R. Leiffer
