Our Vision

Imagine people freely and creatively sharing Christ with a lost world.

Imagine what could be accomplished if believers could overcome their fears about sharing Christ.

Evangelism in Depth Ministry (EID) promotes the concept of Total Mobilization - preparing the believer to give a verbal testimony of their faith in Christ, while assisting the local church in establishing a new attitude about evangelism.

Utilizing seminars or conferences where Biblical principles and concepts about evangelism are clearly presented, EID helps believers realize their natural evangelistic abilities, as well as overcome their fears and worries about sharing Christ.

The result is a multiplication of Christian communicators, excited about fulfilling God's command to share Christ with a lost world.

The concept of totally mobilizing believers for evangelism was originally developed in the 1960's and put successfully into practice in Latin America by Kenneth Stracken, the past President of the Latin America Mission.

The late career missionary and evangelist Rev. Juan M. Isais expanded the work, presenting these ideas in the ministry of Evangelism in Depth for over 40 years. Evangelism in Depth continues to have an impact in the United States, Latin America, Africa, India, Nepal and the Philippines.

Evangelism in Depth is now directed by National Boards with the vision of seeing the Total Mobilization of all believers: giving their testimony within the framework of the local church, under local leaders, with global objectives.

The ministry of Evangelism in Depth is also working to establish a National Headquarters in every nation to accomplish a worldwide evangelistic movement.


The secret of Evangelism in Depth is the agonizing prayer of the believer and the constant action of reaching others with the Gospel. Agonizing prayer is what moves resources, people, organizations, and institutions. Prayer is the key that opens all the doors of Heaven. Prayer changes things and that is why it is an essential part of the EID ideology.

Statement of Faith

  • We believe the Bible is the inspired and only infallible, authoritative Word of God.
  • We believe that there is one God, eternally existent in three persons: Father, Son, and Holy Spirit.
  • We believe in the deity of our Lord Jesus Christ, in His virgin birth, in His sinless life, in His miracles, in His vicarious and atoning death through His shed blood, in His bodily resurrection, in His ascension to the right hand of the Father, and in His personal return in power and glory.
  • We believe that for the salvation of the lost and sinful men repentance and faith in Jesus Christ is the only way.
  • We believe in the present ministry of the Holy Spirit by whose indwelling the Christian is able to live a godly life.
  • We believe in the resurrection of both the saved and the lost: of them that are saved unto the resurrection of life, and to them that are lost to the resurrection of the damnation.
  • We believe in the spiritual unity of believers in our Lord Jesus Christ.
