Evangelism Explosion (EE) is a Christian evangelistic discipleship ministry and training program.

[1][2] Evangelism Explosion was started in 1962 by D. James Kennedy, senior pastor of Coral Ridge Presbyterian Church.

As a result of this, Evangelism Explosion announced that it was "changing its approach to emphasize relationship-building and discipling new believers.

[9] The latter is designed especially for members of Generations X and Y. Evangelism Explosion is best known for its two "diagnostic questions" that users can ask non-Christians as a means of determining a "person's spiritual health",[10] and of stimulating an evangelistic conversation: After the diagnostic questions, the evangelist is encouraged to explain the gospel in terms of grace, man, God, Christ, and faith.

[16] David L. Larsen suggests that Evangelism Explosion has "brought a quickening of the evangelistic pulse", and has "provided a most helpful and practical vehicle for witness."
