John on Patmos
On the small island of Patmos, off the coast of Asia Minor, John sees the visions written in the book of Revelation.
In the beginning God created the heavens and the earth. Now the earth was formless and void, and darkness was over the surface of the deep. And the Spirit of God was hovering over the surface of the waters. And God said, “Let there be light,” and there was light. And God saw that the light was good, and He separated the light from the darkness. God called the light “day,” and the darkness He called “night.” And there was evening, and there was morning—the first day.At the same time in the world
Printing from carved wooden blocks was centuries old in China, and Korea printed books with metal type before 1400. In Europe Gutenberg brought together a press, metal letters cast in a hand mold and an oil-based ink. His Bible was the first major book printed in Europe with movable type. Here is the world of the mid-15th century.
