The Mama Bear Apologetics Guide to Sexuality and Gender Identity is an invaluable handbook for training your kids to know and respect God’s truth in a world that doesn’t. Expanded and revised with updated research and two brand-new chapters, this book will equip you to

  • understand God’s design for gender, sex, marriage, and family as a beautiful reflection of His nature
  • identify the tactics that distort biblical sexuality under the guise of Christian-sounding words, such as love, identity, tolerance, and justice
  • teach your kids to show Christlike compassion to others while upholding biblical truth
     

As society continues to blur the lines of what is good, true, and acceptable, God’s standards remain clear and unchanging. This book will give you the wisdom to confidently raise your children to understand sexuality and gender identity through a biblical lens.

Making Sense of Nonsense:

Navigating Through the West’s Current Quagmire

-Contributing Author

In recent years, there has been a concerted attack on many of the precepts of Western
civilization relating to the concept of God, truth, Christianity, morality, sex, the family,
and even modern science, especially biology. The concern of this volume is to explore these
and other attacks through the tools of philosophy, theology, science, and intuition. It seeks
to bring clarity to the ongoing struggle of Western civilization to preserve its values and
traditions.

The West is crumbling at an accelerated rate. The unfolding erasure of history, objective
morality, and truth has paved the way for our current predicament. We are now standing
at the precipice of the future of human civilization. The attacks on the human person
are unrelenting, malicious, multifaceted, and wide-ranging in their scope and breadth,
from the time prior to birth until the moment of death. If you are granted the “right”
to live, then you must be prepared for unending assaults on your, mind, body, and soul…

Answering the Music Man:

Dan Barker's Arguments against Christianity

-Contributing Author

Dan Barker, ex-preacher and co-founder of the Freedom From Religion Foundation, travels widely, arguing in debates and speaking on his beliefs that Christianity is false, God does not exist, and the Bible is filled with errors and mythology. He has been touted as one of America’s leading atheists. Yet close examination of his arguments shows that Barker’s reasons for disbelief are poorly reasoned and miss the mark as they are aimed at a mistaken caricature of Christian theism. Answering the Music Man exposes Barker’s misunderstandings of Christianity and provides compelling answers to Barker’s arguments.
