During Dennis McCallum's first year in college he began taking his friends to home Bible studies he and friends had formed. As the group developed they also began a publishing enterprise. When their group grew to include several high school and adult home groups in the central Ohio area, Dennis realized his need to get more training He completed his seminary training at Ashland Theological Seminary and returned to continue developing the group in Columbus, Ohio.Dennis and his colleagues formed a new ministry group in 1994 called "The Crossroads Project," to teach apologetics to the church at large. Their book, The Death of Truth (Bethany House) addresses the subject of postmodernism, which they call the guiding spirit of our times. They show that American society has forsaken truth, that reason and rationality are viewed as cultural biases, and that truth-especially God's truth-doesn't exist. Dennis McCallum, with others from Xenos also presents a Postmodern Challenge Conference at universities throughout the countryDennis, his wife and children are all involved in activities and ministries in Xenos. They make their home in Ohio.
