Lucado attended Abilene Christian University where he received an undergraduate degree in Mass Communication. While a student at Abilene Christian, Lucado worked to pay his way through college by selling books door-to-door with the Southwestern Advantage entrepreneurial program. Initially he wished to become a lawyer, but has said that a required Bible course at the university and a mission trip made him change his mind, deciding instead to become a missionary. However, this required that Lucado get a graduate degree in Bible and Biblical Studies, and have at least two years experience ministering to a church. Lucado graduated from Abilene Christian University with a master’s degree in Bible and Biblical Studies.
After graduation, Lucado became an associate minister at Central Church of Christ in Miami, Florida. His responsibilities initially included overseeing a singles’ group and writing a column for the church’s newsletter. After two years in Miami, the now newlywed Lucado and his wife, Denalyn Lucado, moved to Rio de Janeiro, Brazil to become full-time missionaries. In 1987, Lucado’s father died from Lou Gehrig’s disease. After five years in Brazil, he brought his family back to the United States to be closer to his mother.
