Karl's Books

In addition to writing prolifically for Kidology.org, Karl Bastian has published a number of curriculum and books of interest to those in children’s ministry.



Kidology Theorems Book

The term “Kid-ology” was created by Karl in the mid-90’s as a rookie kids’ pastor. It describes the “science of ministering to kids” which comes out of his desire to continually be learning the best ways to teach God’s Word and minister to kids from within their own culture.

After decades of experimenting, research, trial and error, Pastor Karl, also known as the “Kidologist”, has compiled 50 Ministry Theorems he has discovered in the laboratory through weekly hands-on ministry.

Apply these theorems to your kids ministry, experiment with them, tweak them in your own laboratory, and watch as success bubbles up like you’ve never seen before.

Stickers Through the Bible

This revolutionary concept allows non-readers to feel like they are “reading” and mastering the Bible, even before they can read. Preschoolers will learn basic Bible facts and gain an understanding of the overview and flow of God’s Word and a fundamental mastery of the Book. The advantages this will give them later in their Christian life are significant; most of all, a love for God’s Word and a desire to be able to read it! Learn More



As an adoptive dad, Karl wrote Apdopted to explore Bible characters that were adopted, from Moses to Jesus. The theme of this lesson is based on Ephesians 1:5: "His unchanging plan has always been to adopt us into His own family by bringing us to Himself through Jesus Christ. And this gave Him great pleasure."




Curriculum not listed in detail such as these for Easter and Thanksgiving and a Christmas Play. As well as various Kid's Church individual units available in the Kidology Store and many games such as the Bible Clue Hunts.
