Guiding Principles For Integrally Christian Engineering Work In Industry, Justin R. Vander Werff

Faculty Work Comprehensive List

What is integrally Christian engineering? Or to ask it slightly differently, what does engineering look like if it is faithful and obedient to God’s will as revealed in His Word? I do not think we, as finite and creaturely Christ-followers, can expect to exhaustively determine God’s biblical directive for every facet of engineering and technology on this side eternity. However, if we truly believe that Christ is Lord of all of life and that He calls us to grateful service in everything we do, we need to continue to wrestle with these questions. One framework to help navigate these questions …
