Man Up! is a book for men who want to know how to be truly masculine and what that means and have grown up in a society that has "simply lost - or forgotten - the collective knowledge of what it means to be a man."
Regardless of how you take his straightforward writing style, Walsh's thesis is clear: The religion of liberalism has become the new, sandy foundation of our society, and we Christians let it happen.
Our self-righteousness is in dire need of a wake-up call, and that is what this book is for. It is an insightful "wake-up call to complacent Christians," convicting us to acknowledge and wrestle with what we actually believe and what we are called to believe and live out.
