The document outlines a 40-day initiative aimed at understanding and reaching diaspora peoples in the USA, emphasizing the importance of addressing the needs of over 20 million unengaged and unreached individuals living in urban areas. It highlights the increasing presence of migrants, particularly from 'unreached' regions, and the need for targeted missional efforts within U.S. cities. The initiative invites churches to engage in prayer, education, and cross-cultural outreach to further the mission of spreading the gospel among these populations.
