Some people may wonder why a group of people trying to serve a poorer nation would suffer what they did last week.
Many of you, I'm sure, have felt a deep sense of sadness for the families of the group of 19 who were involved in the crash in Kenya on Tuesday.
A van rolled in heavy rain and ended up in a ditch, killing Tauranga couple Brian and Grace Johnston, former Bethlehem College student Caitlin Dickson and their Kenyan driver.
A teacher at Rotorua's Chapman College, Gemma Tong was in the crash and suffered a broken arm. Others in the van suffered various injuries.
How do you explain why a couple like the Johnstons, who had given so much, were taken, leaving behind 10 children who are now orphans?
