The idea is that by praying for Muslims we will see their hearts open to the gospel, and the 30 days is the time of the fasting month of Ramadan. For each of the days there is a special topic to pray for, related to Muslims in different parts of the world. Here are testimonies of how Muslims have come to faith in Jesus as Lord and Savior.
For 25 years the prayer booklet has been published, and in those 25 years a movement of Muslims coming to Christ has taken off. Use the booklet every day in Ramadan, and feel free to request more for those you know who would like to join you in prayer. This way you can be part of a worldwide prayer campaign and you will see God doing great things!
