About DTI

Discipler Training International is a non-denominational discipleship ministry, providing free discipleship resources for training disciplers (spiritual mentors) to help every Christian grow in spiritual maturity, spiritual fruitfulness and spiritual reproduction.

Colossians 1:28-29 (Paul wrote) We proclaim Him, warning and teaching everyone with all wisdom,  so that we may present everyone mature in Christ. I labor for this, striving with His strength that works powerfully in me. 

John 15:8 (Jesus said) My Father is glorified by this: that you produce much fruit and prove to be My disciples.

2 Timothy 2:2 (Paul wrote) And what you have heard from me in the presence of many witnesses, commit to faithful men who will be able to teach others also.

Our goal for this App is to provide our "Tool for Personal Discipleship" to digitally-savvy individuals seeking to promote personal discipleship and help believers  toward spiritual maturity and spiritual fruitfulness.  Art Barkley, author

ABOUT THE AUTHORS Art & Toni Barkley    

Art & Toni became Christians in 1961 in Salt Lake City, Utah, and later, served as missionaries in Bolivia, South America, for about 20 years with New Tribes Mission. That’s where much of the groundwork for this discipleship material was set.

The Lord changed the direction of their ministry in 1991 when He arranged for Art to spend the next 7-1/2 years as an associate pastor at Reno Christian Fellowship (RCF) in Reno, Nevada. During that period, God took Art through a learning experience in the area of discipleship (spiritual mentoring) that changed his entire perspective.

Art founded Discipler Training International (DTI) in 1999, resigning from RCF to focus full-time on the ministry. He authored the discipleship manual A Tool for Personal Discipleship” under the direction of the Holy Spirit. Art and his wife, Toni, continue to promote discipleship concepts and the training of disciplers  around the world, as well as personally discipling men and women.  

The purpose of this discipleship material is to provide believers who have a passion for the Lord, with a Tool to use under the direction of the Holy Spirit, to help other believers to grow and experience the joy of the Normal Christian Life.  We have heard many believers lament, “I would like to be used by the Lord to help other believers to grow spiritually, but I don’t know what to teach.” This Tool is designed to help address that need.

In subsequent years, Art has been involved to varying degrees in the personal discipleship of hundreds of men. He and Toni have seen God change lives and count it a privilege to have a small part in God’s plan to grow and use believers through Personal Discipleship.

Art Barkley is President of Discipler Training International, and his wife Toni is involved in spiritual counseling and discipling women.
