Many will see the power of the False Prophet as a sign of his authenticity. But biblical scholar Craig Keener warns against accepting miracles alone as validation of an authentic prophet of God: “Signs by themselves can be positive or negative; what enables us to discern true prophets from false ones is . . . to evaluate them by their moral character. The point is that we know them by their message and their fruit, not by their gifts (Deut. 13:1–5; Matt. 7:15–23).”4
