The Lost
Jesus has commanded us to reach all people groups with the Gospel. Unfortunately, much of the world still does not understand the basic Gospel message of God's holiness, man's sin, and salvation in Christ.
Indigenous Leaders
Because life is short and the need is so great, we should train trainers and teach teachers who can multiply our teaching ministry until Jesus comes.
The Church
Only as Christians become aware of needs will they be moved to meet them. So, we teach, preach, and take missions teams so that they can learn how their lives can be used by God to impact His world.
Welcome!

All of God's people going into all the world faithfully obeying all of the Great Commission.
Jesus commissioned us to reach and teach all people everywhere. We teach, preach, and take missions teams so that individuals can learn how their lives can be used by God to impact His world. On this website you will find information about many aspects of this great task to which we have been called.
You will find information here about ministry trips as well as links to resources that can enable you to find and fulfill your role in making disciples, training trainers, and teach teachers. Perhaps God will use this information about a location or resource to call you to be involved in indigenous leadership development or lead you to contact RTIM to assist your church or ministry through a consultation.
It is my prayer that the various resources on this site would honor Christ by equipping His people to bring glory to Him among the peoples of the earth. Please contact us with any questions you may have about how we can partner with you in this task.
Soli Deo Gloria,
David Sills

- "2012 Peru Pastor's Conference"
2-2-2012 - “Brother, please come out to the jungle and teach our pastors!” Wilmer implored during a break from my teaching sessions. He is a Peruvian pastor who has served for several years in the jungle. He grimaced embarrassingly as he shared the sad plight of pastors and churches in the area where he served, explaining that many simply used dreams to interpret the Bible, or to know what to preach in their small congregations. . .

- A Call to Great Commission Obedience

While evangelism and church planting are essential components of a biblical missions program, they are merely the first wave of the task to which we have been called. Reaching and Teaching surveys contemporary missions methodologies and advocates a return to the biblical task of reaching and teaching the nations for Christ’s sake.

- Find Your Place in God's Plan for the World

Christians of all ages recognize the heartbeat of God to take the gospel to the nations—yet they often wrestle with the implications of the Great Commission in their own lives.
