Delphine grew up in a secular Jewish home and came to faith later in life after attending a Billy Graham crusade. She was one of thousands that stood up at the altar call. Delphine never quite understood her Jewishness until coming to work with Jews for Jesus. That was one of the motivating factors for her interest in the mission. Jews for Jesus is where she met her husband Joshua. Delphine has a master’s degree in American Literature from the Sorbonne in Paris.
