Introduction

Jesus Christ gives his disciples the Great Commission:
       Go and make disciples of all nations (Matthew 28:18-20).

With this course we wish to contribute to this and to help you to do the same.
The purpose of the Delta course is to put Ephesians 4:11-16 into practice:
       ...to prepare God’s people for work of service,
       so that the body of Christ may be built up
(verse 12).

Preparing people for work of service (equipping them) concerns three areas:

  • Knowledge of the Bible
    The history of salvation is followed in two series of 15 lessons.
    The Delta course follows God’s acts and his words from Genesis to Revelation:
    From the creation and the fall into sin in the Old Testament to the life of the Church and the second coming of Jesus Christ in the New Testament.
  • Practical discipleship
    This part deals in 20 lessons with important aspects of being a Christian:
    your daily contact with Christ, assurance of salvation, how to do Bible study, how to find God’s will for your life, etc.
  • Leadership
    The lessons have been set up to practise also the different subjects together.
    After having finished the course you will be able to start and lead a group yourself.

On this site you find the full text of the online discipleship training Delta Course:

All 50 lessons contain:

  • preparation materials for the students
    (i.e. suggestions for quiet time and an accompanying study),
  • guidelines for the group leader for leading the meeting.

For finding your way in these materials we have added:

  • a short Overview of the 50 lessons of the Delta course (PDF),
  • an extensive List of topics that are covered in these 50 lessons (PDF).

This Delta Course has been used for many years and in several continents where it has proven its worth.
