On July 25, 1982, Pastor Jaerock Lee opened Manmin Church in the obedience to the Word of God who told him to 'open the church when the sun was scorching.'

Pastor Lee devoted himself only to the Word and prayer before the opening of the church. He offered up immeasurable amount of prayer and fasting with faith and love, and he received power even before he opened the church. Many signs and wonders unfolded, and the members prayed every night in the sanctuary and diligently helped the needy. And after four years the number of the church members reached three thousand.

In the year 1986, Pastor Lee was ordained, and the church began the literary media ministry with the publication of his testimonial memoirs Tasting Eternal Life before Death and Manmin News. And he also led many revival meetings in Korea. When he led The Advent of the Holy Spirit Meeting in Juam Mountain Prayer Center in May 1990, many people were blessed through his message and experienced powerful works. There were several who asked him to open branch churches in their areas.

In July 1991, the United Holiness Church of Jesus Christ was organized in the providence of God, and since then the church accomplished national evangelism and world mission by participating in many events; World Holy Spirit Crusade 1992, Washington Evangelism Crusade 1993, Africa Pastors and Church Leaders' Seminar 1994, Seoul Holy Spirit Crusade 1994, Iida Crusade 1994 in Japan, LA World Mission Crusade 1995, Jubilee Crusade in the 50th Anniversary of Independence 1995, Crusade and Pastors' Seminar for Korean Churches in Hawaii 1996, Blessing Crusade for Koreans in Argentina 1996, and Argentina Pastors' Seminar and Revival Meeting 1997.

In particular, from 2000, Dr. Jaerock Lee was invited to lead overseas crusades in many countries: Uganda, Japan, Pakistan, Kenya, the Philippines, Honduras, India, Russia, Germany, Peru, DR Congo, the U.S., Israel, and Estonia. He proclaimed God the Creator and Jesus Christ and performed signs and explosive power.

In 2007, the church started the Israeli ministry. Dr. Lee began to spread the holiness gospel with manifestation of powerful works all over the nation. In September 2009, he led Israel United Crusade in Jerusalem.

In addition, the church's ministry has actively continued in several different modes. A few examples are GCN (www.gcntv.org), a TV broadcast channel that covers 170 countries, Dr. Lee's books in 61 languages, World Christian Doctors Network that confirms the divine healing cases based on medical data, and Manmin International Seminary.

This church now has become a global mega-sized church which has 11,000 branch and associative churches all around the world. The ministry is to be extended to accomplish the providence for the end time, which is to lead all people of all nations to salvation with the Holy Spirit's power of re-creation.

On July 23, 2017, the church had its 35th Anniversary of the Church Opening Celebration Performance during Sunday Evening Service and glorified God who has led Manmin for the last 35 years.
