Ron Post was an ordinary businessman when his life took a sudden, unparalleled turn, dramatically altering his life direction and challenging his faith.

Ron and his wife, Jean, were watching the news showing the emaciated body of a dead teenage girl carried from a field in Thailand. Horrified by the devastation ensnaring a mass populace of Cambodian refugees during the "Killing Fields" of 1979, Ron and Jean were heart-stricken.

At that moment, God spoke in Ron a clear directive that began his harrowing forty-year mission to serve the neediness in forsaken regions worldwide. Unchained is Ron's real and raw experiences in the center of massive human displacement, starvation, illness, injury, death, and grief-the atrocities of wars, natural disasters, disease, congenital malformation, and the work of those who gave selflessly to save and assist millions of lives.

Unchained also carries readers through Ron's journey of overcoming childhood abuse and hopelessness. Releasing the past by forgiving and learning to love those who hurt him freed Ron to find true meaning and purpose in life-helping and serving others.

The healing of Ron's heart ultimately readied him for God's extraordinary and unexpected call: to found and lead Medical Teams International, which continues to serve the needs of those who otherwise lack medical care, food, clean water, a voice, and love. Ron has witnessed God's miraculous work among the worst human conditions and discovered the source of utmost fulfillment and joy. All resulted from one word of response to God, "Yes," that moved him out of his comfortable chair with one resolve: to give his all to those most in need.
