Unshakeable Foundation in Christ: Joshua Muthukumar on Spiritual Fitness & Victory Over Struggle

In this deeply moving episode of The Amazing Authorities Podcast, host Mitch Carson interviews Joshua Muthukumar, bestselling author of Unshakeable Foundation in Christ. Despite being visually impaired, Joshua spent years writing his debut book—a powerful guide on aligning the spirit, soul, and body to experience lasting transformation through faith.

Joshua shares how his passion for spiritual fitness was inspired by his pastor, and how real-life case studies—including one man overcoming depression in just 10 days—demonstrate the impact of applying biblical principles and action steps. Through heartfelt storytelling, practical exercises, and unwavering faith, Joshua proves that limitations can become launchpads for purpose.

🔑 You’ll discover:

• The meaning of “spiritual fitness” and why it’s just as vital as physical health

• The life-changing results readers have experienced through Joshua’s book

• How writing became a healing journey—and a tool for global impact

• The strategic power of choosing the right foreword writer

• How to build authority in the Christian and personal growth space with your book

Whether you're navigating adversity, writing your first book, or searching for spiritual direction, this episode will strengthen your resolve and renew your hope.

A graduate of Rhema Bible Training Centre (Singapore), Joshua has overcome unimaginable odds – from dangerous accidents to rapidly deteriorating vision (congenital glaucoma), to chronic asthma to kidney failure and to being weakened by frequent haemodialysis. Yet he lives life to the fullest, his unwavering faith resting in the finished work of the Lord Jesus Christ at Calvary and His unfailing love for Joshua.
