In Saudi Arabia, a nation historically closed to the Gospel, Christianity is growing faster than the global average. Despite strict bans on evangelism and the threat of severe punishment, including execution for apostasy, underground churches thrive, with some estimating Christians could represent up to 10% of the population. Oswaldo Magdangal, who pastored an underground church for eleven years, reports remarkable growth, particularly among younger Saudis. The secret congregations include native Saudi believers, with some becoming pastors. Recent reforms under Crown Prince Mohammad bin Salman have softened the kingdom's religious rigidity, including curbing the religious police and allowing Bible printing. Testimonies like Ahmed Joktan’s, who encountered Jesus in a dream, and the bravery of Christian tentmakers and underground leaders highlight the Spirit’s work in this challenging environment. Revival stirs as Christians boldly share their faith, while global prayers continue to support this growth. Oswaldo’s own story of near execution in 1992 underscores the resilience of faith under persecution, inspiring hope for the church’s future.
