I love the combination of John Piper's commitment to sound doctrine, Reformed Theology, the glory of God, the Gospel, and evangelism and missions, especially his zeal and commitment to missions to the Muslim world.

Samuel Zwemer, "the apostle to Islam" was a Calvinist and a missionary to Arab Muslims for many years - in Basra, (today in Iraq), Arabia, Egypt, Bahrain. (years in the Muslim world: 1891-1929) See here for a synopsis of his life and ministry and notice the external links at the end of the article. His books are still used to today to for helping understand Islam and Muslims and evangelism to Muslims.
William Carey, missionary to India, was a Calvinist and a missionary. See here for a synopsis of his life and ministry. He wrote the famous little book, "An Inquiry into the Obligation of Christians to Use Means for the Conversion of the Heathens". He went to India in 1792, and ministered mostly among Hindus. He argued for "Means" - for a mission society of several men who would band together for preparation, training, prayer, actually going and learning languages and for the local churches to support such a group/society. This was the very first denominational mission agency. He worked on several NTs being translated into several languages, the most notable was his work on the Bengali New Testament. He was a key force in making Sati (the Hindu custom of burning widows alive with their dead husbands) illegal in India and Hindu culture. He even had an Indian Postal stamp done by the India government in his honor. William Carey is called "the father of modern missions" by Evangelical Protestants. He also made the famous statement, "Expect Great Things From God, Attempt Great things for God!" See the many biographies written about William Carey.
Henry Martyn, was a Calvinist-Anglican missionary to Persia (Iran) and India, and his work on the Persian (Farsi) New Testament was the first time that the full New Testament had been translated into Farsi in history! He died in 1812 after he finished his work on the NT in Persia, on his way back from Persia to England. He died of fever/pneumonia in Tokat, Turkey at the age of 29, trying to get back to England. He is the one who said, "Let me burn out for God".
William McElwee Miller was a missionary and a Calvinist to Persia (Iran) for 40 years. (1920-1960) His books are still motivating Christians today to go to the Muslim world and preach the gospel to Muslims. He also wrote one of the first analysis of the Bahai faith done from a Christian view point.
The Bahai Faith: Its History and Teachings
David Brainard was a missionary to American Indians and a Calvinist.
Charles Spurgeon was a pastor, effective preacher, evangelist and a Calvinist for many years in England.
D. James Kennedy was a Presbyterian Calvinist and wrote a whole book on Evangelism called "Evangelism Explosion" and trained many in Evangelism.
Dr. James White is a Calvinist and has done evangelism for years with Mormons, Jehovah's Witnesses, atheists, Roman Catholics, and more recently, with Muslims, and his debates with them and others are very helpful for others to study and be equipped.
And there are many others! Don't say "Calvinism hinders evangelism and missions!"
