Through the work of Holy Spirit, every May God has performed signs, wonders, with power, so that the Manmin members could lead thrilling Christian lives and blessed them to be overjoyed with hope for Heaven.
In May 1978, the Senior Pastor of Manmin Central Church, Dr. Jaerock Lee, was called by God as a pastor after he met God and received healing of all his diseases at the end of 7 years of suffering. He entered a theological seminary at an older age, armed himself with the Word of God and prayed. He opened a church with the heart of whole spirit having been achieved.
In May 1984, Dr. Lee began receiving detailed explanations about Heaven as the answer to his countless times of fasting and prayer. Consequently, his books Heaven I & II were released, and now the books have been translated and published in 14 languages, which are leading innumerable souls in the world to the way of salvation.
In May 1986, Dr. Lee was ordained as a pastor and began to work in earnest as a witness who preaches the holiness gospel to the remotest part of the earth. He has worked to achieve the national evangelization and the world mission.
Beginning in May 1993, the two-week consecutive Special Revival Meeting was conducted on an annual basis. In the meetings, dozens of couples received the blessing of conception all at once. A man had become disabled and diagnosed with a first class disability and had not been able to sit and stand up for himself. But he came to walk, and jump on his own feet in the meeting. In addition to them, other people were healed of incurable and terminal diseases such as cancer and AIDS. Others recovered from poor eyesight, the deaf came to hear and the mute came to speak. The stunningly powerful works occurred in the meetings.
In May, 1998, the 6th two-week consecutive Special Revival Meeting was held under the title of 'God is Light'. God blessed the church members to see a circular rainbow around the sun that symbolizes a rainbow that is around the throne of God described in Revelation 4:3. Since then, triple and fourfold circular rainbows have appeared and many other shaped rainbows such as linear, symmetric, asymmetric, K-shaped, and ring-shaped rainbows have beautified the sky.
In May 2004, as the Special Revival Meeting was in progress with the theme "Thundering the Original Voice", GCN (Global Christian Network) TV embarked upon its mission and the event opened the door to the international broadcasting ministry. Additionally, it started the ministry in Israel which had been a debarkation point for preaching of the gospel but became the remotest part of the globe in the preaching.
Since May 2011, pictures have been taken in and around the church of the aurora-like lights with beautiful images that have been captured on members' mobile phones. The image of the Lord is shown, and there are many abounding shapes in colors such as flowers, musical notes, fish, hearts, and blessing bags that evoke the heavenly beauty. The aurora-like lights encourage the members to long for the beautiful heart of spirit that resembles that of the Lord, and to grow up in faith quickly. God of love blesses them always so that they can feel the spiritual world.
Since the beginning of 2013, the 'original voice' has been issued through which the members have experienced amazing healing works and answers. In answer to Senior Pastor Dr. Jaerock Lee's prayer at his mountain prayer house, in May of this year the God of love allowed a few of the church members full of God's grace, to visit Heaven and Hell and testify to what they saw.

In May 1998, a circular rainbow appeared around the sun. In 2010, a ring-like rainbow and in 2011, a comprehensive rainbow appeared. God has shown such extraordinary and varied rainbows to the members.


In May 1984, God described in detail Heaven and the crystal-clear and beautiful New Jerusalem, in May 2004, the two-week consecutive Special Revival Meeting was held under the title of "Thundering the Original Voice", and in May, 2013, God blessed the members to experience the spiritual world through the separation of spirit.


Since May, 2011, the church members have taken photos of the original lights with the images of the Lord and angels and increased hope for the best heavenly dwelling place New Jerusalem.
