Isaiah promises, “They shall not hurt nor destroy… FOR”—Hebrew kî (“kee”), “because”—“the earth shall be full of the knowledge of the LORD as the waters cover the sea.” That little word reveals the hinge: when the world comes to know God and His ways, the world changes—government, war, fear, justice, the earth, and human life itself. This is more than an information revolution; humanity will come to know God, while Satan will no longer deceive the nations. We have the extraordinary privilege of learning now what the world will learn then.
