This document provides an overview of a talk on influencing culture from a Christian worldview. It discusses that Christians are called by God to shape culture, but that the church has at times lost influence by failing to equip believers to see their work and callings as ministry. It highlights challenges facing America's moral and spiritual foundations and provides examples throughout history of how engaged Christians influenced culture for good through acts like prayer, networking, addressing problems, and pursuing a strategy of engaging all sectors of society.
