Instincts by Design | November 16, 2023

The guest on this edition of Crosstalk has written a fascinating and captivating book with strong evidence that we have a wonderful and wise creator, as Scripture points to in Romans 1:20.

E. Howard Callahan is a retired chemical engineer who spent years working in the fields of chemistry and biology.  His research and development work revealed  to him that God indeed made the world.  He’s done R&D work on aloe vera, learning of its many uses in humans, also R&D for an anticancer drug-delivery system.  He also helped develop and manufacture an artificial scab for very large wounds.  As a Christian, he’s spent over 60 years studying the Bible and how it applies to our everyday lives and holds a master’s degree in theology.  He is author of the newly released, Instincts by Design: Instinctive Behaviors of Humans & Animals in Creation.

In preparing to write his book, Callahan discovered that instincts are more complex than he thought.  Instincts are built into the DNA (atheist scientists agree) with the information being like a computer program.  When called upon, it will cause behavior that’s important for the life, growth or protection of the creature.  

As he looked at research from non-believers, he saw a critical error they’d make.  Most of them believe in evolution rather than God, so evolution wouldn’t fit with some of the words they were using.  In their descriptions they would slip up and use words and phrases such as “miracle,” “designed,” “extraordinarily complex,” “uniquely constructed” or they’d say that something is “largely unknown.” 

While proof of God’s design should be obvious, we often don’t see it.  As Callahan said, “It’s the elephant in the room.  It’s there and we just ignore it.  We just say it’s instinctive and then go on.”  

Skeptics will hear proof and believers will rejoice to learn the following: How does your nose protect you from harm?  How do instincts (like sonar) help animals find their food?  How do birds know how to migrate and fly in the “V” formation?  How do instincts play into our switch from breathing liquid while in the womb, to air outside the womb just seconds after birth.
