Arguing for the need both to preach Christ in every sermon and to preach regularly from the Old Testament, Greidanus challenges preachers to consider the Old Testament not only in its own historical context but also in the context of the New Testament.

Sidney Greidanus is professor emeritus of preaching at Calvin Theological Seminary and the author of several books, including The Modern Preacher and the Ancient Text, Preaching Christ from the Old Testament, Preaching Christ from Genesis, Preaching Christ from Ecclesiastes, Preaching Christ from Daniel, and Preaching Christ from Psalms.
