David Platt knew something needed to change. He couldn’t see the things he saw in the Himalayas and return home the same man. His trip to the top of the world brought him face to face with the harshest physical and spiritual realities on earth. Children died of treatable diseases. Christians were stoned for their faith and tossed off mountain cliffs. Bodies were hacked to pieces and fed to animals. The trip taxed Platt physically, emotionally, and especially spiritually as he wondered, Where is God in all this tragedy and idolatry?
