I'm sure you know the running joke about fishermen exaggerating the size of their catch. But in 1959, Alfred Dean didn’t need to exaggerate when he caught a 2,664-pound great white shark in Australia, the largest fish ever caught in history. The Bible tells us about an even more unbelievable story, but in reverse—the story of a fish that caught a man. Jonah’s encounter with the great fish would make worldwide news today, but here’s what might surprise you: The fish story isn’t really the point. The book of Jonah is actually the missionary book of the Old Testament, revealing that God has a missionary heart and every Christian is called to be on mission. I like how John Stott said, “We profess to believe in God? He’s a missionary God. We’re committed to Christ? He’s a missionary Christ.” The truth that applies to us today is simple: We all are called. Every Christian has a mission to perform, a message to proclaim, a ministry to promote, and a Master to praise.
