On a warm Thursday afternoon in May, the ululation, drumming and singing of a choir of two-dozen women can be heard across Gan Gora, a village so small it barely appears on the Nigerian map.
“We are happy you arrived safely,” they sing in Hausa welcoming the visitors to the community branch of the Evangelical Church Winning All (ECWA), hidden in the hilly Zangon Kataf, an area of half a million residents in the state of Kaduna.
