How God Used Discovery to Spread the Gospel to the Ends of the Earth
The Age of Exploration, spanning roughly from the 15th to the 17th centuries, was one of the most transformative periods in world history. European explorers sailed to previously unknown lands, establishing trade routes, colonies, and — most importantly from a providential perspective — carrying the Gospel to the far corners of the earth.
While the motives of explorers were mixed — including the desire for wealth, power, and glory — God's overarching purpose was being fulfilled. The same ships that carried gold and spices also carried missionaries, Bibles, and the message of salvation. As Romans 8:28 reminds us, God works all things together for good according to His purposes.
Portugal led the way in exploration under Prince Henry the Navigator, who was motivated by both commercial interests and a desire to spread the Christian faith. Portuguese explorers established trading posts along the coast of Africa and eventually reached India, bringing Catholic missionaries with them.
Christopher Columbus, sailing under the Spanish crown in 1492, believed that God had called him to carry the Gospel across the Atlantic. In his journal, Columbus wrote: 'It was the Lord who put into my mind the fact that it would be possible to sail from here to the Indies... I am the most unworthy sinner, but I have cried out to the Lord for grace and mercy, and they have covered me completely.' Whatever his faults, Columbus saw his voyage as a divine mission.
The Spanish established vast colonial empires in Central and South America. While the conquest brought suffering to indigenous peoples — a moral failing that Christians must honestly acknowledge — it also brought the Gospel. Missionaries like Bartolomé de las Casas courageously advocated for the rights and dignity of native peoples, arguing from Scripture that all human beings are made in God's image.
The English colonization of North America was shaped profoundly by the Reformation. The Pilgrims who landed at Plymouth in 1620 were Separatists seeking freedom to worship according to Scripture. The Puritans who established the Massachusetts Bay Colony in 1630 sought to build a 'city upon a hill' — a model Christian commonwealth that would demonstrate God's principles to the world.
Governor John Winthrop's famous sermon aboard the Arbella declared: 'We shall be as a city upon a hill. The eyes of all people are upon us.' This vision — rooted in Matthew 5:14 — shaped the American identity and the belief that America has a special role in God's providential plan.
Other colonies were founded specifically on principles of religious liberty. Roger Williams established Rhode Island as a haven for those persecuted for their faith. William Penn founded Pennsylvania on Quaker principles of tolerance and peace. These experiments in religious freedom laid the groundwork for the First Amendment and the American tradition of liberty of conscience.
The Age of Exploration opened the door for sustained missionary efforts across the globe. Jesuit missionaries traveled to China, Japan, India, and the Americas. Protestant missionary movements followed in the 18th and 19th centuries, with figures like William Carey, Hudson Taylor, and David Livingstone carrying the Gospel to unreached peoples.
Today, Christianity is a truly global faith — the largest religion in the world — with its fastest growth occurring in Africa, Asia, and Latin America. This remarkable spread, from a small band of disciples in first-century Palestine to billions of believers worldwide, is a testament to God's faithfulness to His promise in Matthew 28:19-20.
The Age of Exploration, for all its complexity and moral ambiguity, was a chapter in the unfolding of God's plan to make disciples of all nations. Christians must study this period honestly — acknowledging both the heroism and the sin — while recognizing God's sovereign hand guiding history toward the fulfillment of His purposes.
Write thoughtful responses to the following questions. Use evidence from the lesson text, Scripture references, and primary sources to support your answers.
How can we see God's providential hand in the Age of Exploration, even when the human motives were often sinful or mixed? What does Romans 8:28 teach us about God's ability to use imperfect people and events for His purposes?
Guidance: Consider examples like Columbus, the Spanish conquest, and the English colonies. How did God use these flawed endeavors to advance the Gospel? How should Christians balance honest acknowledgment of sin with recognition of God's sovereignty?
Compare the Pilgrims' and Puritans' vision for America with the Spanish conquistadors' approach to colonization. How did their different motivations shape the societies they built?
Guidance: Think about Winthrop's 'city upon a hill' sermon versus the conquest-driven model. Consider how the Reformation's emphasis on Scripture and conscience influenced the English colonial approach.
How does the global spread of Christianity from the Age of Exploration to today fulfill the Great Commission (Matthew 28:19-20)? What responsibility do Christians today have to continue this mission?
Guidance: Consider the growth of Christianity in Africa, Asia, and Latin America. Think about how modern technology and globalization provide new opportunities for fulfilling the Great Commission.
