The wave of refugees that started moving to the shores of Europe in 2011 and by 2015 reached flood levels in Germany has changed the churches there. At least, those churches that allowed the flood waters to enter their congregations. As many Christians responded with love and mercy to the refugees and many churches opened their hearts and doors to the strangers, they dared to walk into unknown waters. Suddenly many congregations faced challenges and frustrations nobody could have anticipated, and encountered changes and fears never experienced before. It has also become a new day for the church in Europe. In this book the author speaks from a biblical theology: "God loves the stranger! He told the Israelites to care for the stranger in their midst as if he were an Israelite. He himself became a stranger amongst us to make us citizens of heaven so that, in turn, we would lead strangers amongst us to Him to embrace their true citizenship in Christ."In 2011 Stephen Beck launched a church in Frankfurt, Germany that was swept up in the ensuing refugee wave. Through his experience with the Mosaik Church, and through the experience of many other churches in Europe, he tells us what happens when churches begin to move with God's wave. You will read almost unbelievable stories of God's work with people who walked the refugee trail and what happens when Christians reach out to them and welcome them into their homes and churches. The author takes us through various aspects of the church's ministry and mission, such as evangelism, worship, community life, conversion and baptism, and gives us practical how-to's when Muslims suddenly show up in church and God's people welcome them with open arms and godly courage: a movement.
