In 1980, after what he said was something that he could not turn down, he became a preacher. Piper became Pastor of Bethlehem Baptist Church in Minneapolis, Minnesota. He has been working there ever since. Piper became popular when his book "Desiring God: Meditations of a Christian Hedonist" was published. He has written many books since. In 1994, he started Desiring God Ministries. Today "Desiring God" puts all of Piper's sermons and articles from the last three decades online for free, as well as offering books, CDs, and DVDs.
