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: God Has Been Merciful to Hays Pure Water

John Hays Prayer Letter: God Has Been Merciful to Hays Pure WaterThe Lord Jesus Christ is King of the whole earth! God is merciful to the Hays Pure Water ministry. Nearly 300 Pure-Water Systems have gone out to these countries recently: Togo, Ghana, Malawi, Liberia, Ivory Coast, Sierra Leone, India, and more. Reports are coming in from around the world. See some of the testimonies below:

Pastor George Menyon from the Ivory Coast writes:

“The water machine will really help to bring a lot of people to the church we are now starting here in the Ivory Coast. Thank God for His provision, Sir. God bless you! A church was planted.

Guess what, Brother Hays! Brother Mike and two other missionaries are here with Brother Albert and me in the Ivory Coast. I’m planning to start a church to be named the LIVING WATER BAPTIST CHURCH. Please pray for this, Sir. This will be a memorial for the water ministry!”

Pastor Harris of Togo, West Africa, writes:

“Good morning, Sir. The person standing (middle picture below) is testifying that the chlorine water has greatly improved her health. For the past six days, she had been suffering from a very bad stomach pain and praising God for His healing and also the chlorine generator. The other people are from Togo, a French-speaking country in West Africa.”

Mark Rader, Missionary to Peru, writes:

“In our trip to the Amazon Jungle, 361 people accepted Jesus Christ as their Saviour in 23 villages as a result of sharing the Gospel and treating the river water, using the Hays chlorine machine.”

Please pray that, upon my return from a missions trip to the mountains near Monterey, Mexico, I will have the strength and safety to attend up to 10 more Missions Conferences in 2022. Pray for two missions trips into the Amazon Jungle with Marion Avenue Baptist Church and a separate one into the Solomon Islands, both during the first two months of 2023.

I’m thankful that God lets us reach six new villages daily somewhere in the world! Thank you for your prayers and support!

His water boy,

John Hays
