We have financially supported Mercy Ships for years. These giant ships are floating hospitals. A ship pulls into the port of a developing nation and performs free surgeries. People come from miles around. Many have tumors, deformities, or blindness that never would have reached such a state if they lived in a country with better health care.
Many years ago a Mercy Ship was in the US for repairs and updates, and I was able to tour it. Mercy Ships is also a Christian ministry. They were featured on 60 minutes, and it is more than worth 13 minutes of your time to learn more about them.
