In this modern era, many evangelical Christians have adopted two popular beliefs. First is Christian Zionism-the idea that believers should support modern Israel because it is a fulfillment of biblical prophecy. And second is theistic evolution-the idea that God used extensive evolution in the creation of the universe and living things. While these beliefs are popular, unfortunately they are also dangerous to the faith. In Debunking Christian Zionism and Evolutionary Creation, author Les Nasserden presents two separate essays where he rigorously challenges the biblical integrity of those evangelical Christians who believe in these false doctrines. In the first essay, Les explains why the Christian Zionist project was one of the biggest mistakes evangelical and Pentecostal Christians made in the twentieth century. In the second essay, he calls theistic evolution a heresy and confronts evangelical Christians with a challenge: Are we going to affirm the Word and power of God? Or are we going to capitulate to both a lingering modernist rationalism that is wedded to naturalism, and a desultory postmodern ethos that denigrates truth, the meaning of texts, rationality, and historical realities? Even though many evangelical Christians believe in these doctrines, we need to safeguard our minds against false teachings. But by turning to the authoritative Word of God and studying the scriptures, we can discover the truth and strengthen our integrity.
