Christianity in the founding of America is not confined to the early settlers in the 1600′s. Christopher Columbus in 1492 declared his purpose to be led by the Holy Spirit. The Word of God was his foundation he said. God sent him as a forerunner to prepare the way for those who were to possess the land. Here is a delightful essay that tells the story:
“No one should be afraid to take on any enterprise in the name of our Savior if it is right and the purpose is purely for His holy service.” (Fols. 4-6 of Book of Prophecies by Christopher Columbus)
As a young boy, Columbus trusted Christ as his Savior and discovered the Ways of God. He felt that God wanted him to explore the world and find new land and people so that Christ could be proclaimed. He became an excellent sailor and businessman and overcame many problems with God’s help, even mutiny and being bound in chains.
“All those who heard of my plan disregarded it mockingly and with laughter. . … Who would doubt that this (idea for sailing west) . . . came from the Holy Spirit . . .” In Columbus’ own writing, the “Book of Prophecies,” we have evidence that “the Bible was the principal source of inspiration for the great Columbian enterprise.” (Christopher Columbus: His Life and Discovery in the Light of His Prophecies by Kay Brigham. Libros CLIE, Spain, 1990 p. 53)
The Scripture that Columbus read and believed were the inspiration for his journey around the world. In a written statement from Columbus’ own hand, he testified that it was from reading the book of Isaiah that he discovered that the world is round. Isaiah 40:22 “It is (God) that sits upon the circle of the earth.” At a time when most believed that the earth was flat, it was the Scriptures that inspired Christopher Columbus to sail west. He wrote (from his diary, in reference to his discovery of “the New World”): “It was the Lord who put it into my mind. I could feel His hand upon me … . . there is no question the inspiration was from the Holy Spirit because He comforted me with rays of marvelous illumination from the Holy Scriptures.” (Ibid)
