"The 7th Anniversary Service and Commemorative Performance of Muan's Sweet Water of God's Power" took place at Muan Manmin Church (Rev. Myung-sool Kim, Senior Pastor) on Thursday, March 1, 2007. After a message, titled "Into Spirit and Whole Spirit" proclaimed by Manmin Joong-ang's Assistant Pastor Rev. Mi-young Lee, performances by the Crystal Singers, Student Pastor Jung-ja Choi, and Gwangju Manmin Church's "One in the Holy Spirit" praise and worship team greatly magnified God. The service and the performances were followed by a time of praising at the fountain of the Manmin Sweet Water during which the gathered gave thanks and glory to God.
Seated on an island off the southern coast of South Korea, Muan Manmin Church had been tormented from the lack of plentiful potable water in the past. When Senior Pastor of Manmin Joong-ang Church Rev. Dr. Jaerock Lee prayed for the situation on March 5, 2007, members of Muan Manmin experienced firsthand the bitter and salty subterranean water turning into sweet, drinkable water (Exodus 15:25). Today, found to be rich in mineral and proven to manifest works of healing, the Muan Sweet Water bears witness to the power of the Living God.
For this reason, Muan Manmin Church has been frequently visited by visitors from other parts of Korea and the rest of the world alike.
