In Iran, one of the world’s most dangerous places to be a Christian, the underground church is growing remarkably. Amid an oppressive regime enforcing Twelver Ja’afari Shia Islam, over one million believers now worship in secret, making Iran home to the fastest-growing Christian population globally. These followers meet discreetly in house churches of no more than fifteen people, risking arrest, loss of livelihood, and severe punishment. Stories like Azam’s highlight this courage: shunned for pregnancy outside marriage, she found hope in Christ through a Christian woman’s witness, discovering the One who bears shame and offers new life. Despite surveillance, threats, and societal rejection, Iranian Christians embody a faith purified through suffering, reminding believers worldwide that Christianity is not defined by comfort or buildings but by a willingness to risk all for Jesus. Their example challenges Western believers to strip away distractions and embrace genuine, sacrificial faith. Ministries like ICM partner with the underground church, discreetly distributing Scripture via micro SD cards, ensuring the Gospel continues to spread even in the darkest circumstances.
