'God made a way for my husband and I to build a hospital for the destitute Quechua people of Peru'

From a high school romance to moving mountains in the Andes, Dr Martina John shares how the dream she and her husband shared, became a reality.

I was 16 years old when I met Klaus John at school in Germany. It was 1978 and he was the president of the high school, and I published the school newspaper.

We fell in love, even though we came from quite different backgrounds. I went dancing several times a week and, as a party girl, was always in the middle of the hustle and bustle. Klaus, on the other hand, was involved in children’s work and youth groups in an evangelical free church. But we shared a common dream.
