Project Description




John Birthday 12/06

I grew up in church. I do not remember ever hearing the Gospel. It was in college that I was asked what the Cross of Jesus meant to me. I did not know.  I studied the Bible and realized He loved me and died for my sins. I accepted Jesus as my Lord and Saviour on September 21, 1974. I was baptized shortly after in the university swimming pool. I am now a member of and sent out of Marion Avenue Baptist Church under the leadership of Pastor Joseph Brown.

Farming was my god, but I followed Christ’s calling to enter public water treatment for three decades, starting in 1980 till 2010. He placed on my heart the need to invent and distribute a water-treatment system in 2004. I believe these Scriptures for my ministry:  Matthew 25:35 and John 4.  I serve Jesus in each thirsty person and witness to offer living water. I am in my second decade of this ministry. God has let me manufacture 5,000 systems and distribute them in 50 countries. In Sudan, Africa, for example, 1,200 villages were given both waters.  More information and testimonies can be found at Hays Pure Water.

I began working in the ministry in 2005 and have seen many in 50 countries in 5,000 villages saved, grow in Christ, and become fruitful soul winners. My burden is to reach more around the world with both drinking and living water and to train them to become effective and fruitful soul winners. I have developed and manufacture a water machine that perfectly treats water for up to 5,000 people for several decades.

My desire is to work with the missionaries of Fundamental Baptist Missions International and assist them in planting churches. I want to see people saved and then train them to become soul winners. In addition, I have a strong burden to reach their entire village for Christ. This will be most effective through the water ministry-serving missionaries.

This will take much labor and sacrifice. I am ready to reach more of the world. I invite you to pray and consider partnering with me in this effort through your prayers and finances. Please contact me if you would allow me to share my burden and calling with you and your church.

If I can serve you in any way, please allow me to do so.

In 2006, after traveling around developing nations on missions trips, John Hays was burdened to create a low cost, portable solution for water purification. After reading the historical account of Elisha cleansing the water of Jericho in II Kings 2, John put his 30+ years of experience with municipal water works to use and developed the Khlor Gen system.

Through the years, the design and look has been changed and improved, but the mission has stayed the same. Provide people with clean water, reaching out to them through word and deed. Eight years and 4,000 units later, that mission continues full steam ahead.

John Hays Prayer Letter: Without Your Prayers and the Power of God, My Efforts Are Futile!

John Hays Prayer Letter: Without Your Prayers and the Power of God, My Efforts Are Futile!God is working. We treat non-drinking water using an oxidant generator, which I developed and volunteers make in Iowa. We give the machine freely to those in need at a rate of 6 per day or 1,548 villages so far this year. I estimate 9,000 people have come to Jesus and up to 150 new churches have started. One system treats an entire village. Missionaries give the Gospel during the training. Results keep coming.

I went to Peru with Missionary Zach Foust and Team Peru. We went into the Amazon Jungle and saw many come to Christ. The governor of the jungle and other government officials saw how the Amazon water was treated, and then they heard the Gospel of Jesus Christ! The Amazon Jungle has 480 hospitals and 5,000 villages. Pray that God opens doors and shows us mercy to treat all of the villages, along with the hospitals. We desperately want to keep sharing the Gospel. Pray for funding to be released from Heaven.

Sadai Isaac, from the Republic of the Congo, shares his testimony. He treated water using our Pure Water System and gave the Gospel of our dear Lord Jesus in over 480 villages last year. The results from his efforts are 3,000 new believers and 52 church plants.
Testimonies from Liberia show more people have been reached for Christ. More than 120 souls have accepted Jesus Christ as Lord and Saviour in 35 different villages.

In each testimony, people are in much better health than before. They can go to school, and they can go to work again. Hospitals are emptied of patients with waterborne diseases.

Thank you for many generous donors and prayer warriors. Without your prayers and the power of God, my efforts are futile.

May Jesus be glorified!

His water boy,
