This book is not an exercise in Mission marketing, but an honest upfront account of the first 40 years of EAB (Evangelical Action Brazil), telling when we got it right and when we got it wrong. It is a mark of honour to dedicated missionaries who gave their best for Jesus in north-east Brazil. EAB’s first 40 years covered a period of great change and turmoil. Within a year of the Mission’s founding the Second World War erupted. Later in the period there was the 1964 Coup d’état in Brazil which ushered in 20 years under a military regime. Travel to Brazil in the early years by ship changed to planes. Telegrams were substituted by telephones and radios were joined by black and white TVs. Earth tracks were partially substituted by tarmac roads as the period progressed and vehicles began to replace horses and mules for travel. Electricity was initially generated locally in Patos, but eventually was integrated to the national grid. Water started to be piped to people’s houses rather than being carried by donkeys or carts, though the latter still continues in the interior of Paraíba State to this day. Cesspits linked to holes in the ground were progress from random defecation and still today only 7% of the homes in Patos are linked to the sewage treatment plant. In the religious sphere Catholicism was the dominant force and EAB faced strong opposition to its preaching the Biblical Gospel of Jesus Christ, often violent and always insulting our folk as being part of a dangerous sect. EAB had been directed by God to plant evangelical churches in the poorest, driest and most spiritually barren region of Brazil. We pay homage to those missionaries and national workers who tirelessly served God in an area few wanted to live or work in and we praise God for their lives and ministries.
