Rainbow Discovery – Becoming a Christian Series

Rainbow Discovery

Rainbow Discovery is a zero-cost direct witnessing tool, visual aid and scripture reference system for evangelists. Although witnessing resources exist, it is our conviction that a new imaginative approach is needed. Instant decision techniques are no longer effective because we live in a post-Christian era where most people do not have the Biblical background to receive the gospel in a 30-minute presentation. At the other end of the spectrum are the 20-week course methods which, although useful, demand a heavy commitment on both counsellor and counselee.

Rainbow is a sharp 6-lesson course that steps the seeker through the gospel revelation with power and precision. Anyone can lead their friends to Christ without getting tongue-tied yet still having the flexibility to add their own personality into it. Alternatively, it can be developed into full studies for existing believers.

Key features include: -​

  • Dynamically linked Bible readings.
  • Picture and graphic aids.
  • Key concept boxes.
  • 3 in 1 application.​

Rainbow can be used in several ways: In group settings, or as a ‘good news’ giveaway.  For more on ‘How to Use’, please download Rock Leaders Manual.

River Bible Course – New Christian Series

River Discipleship

River Discipleship is a series of free Bible studies developed for new Christians and others seriously thinking about spiritual things. Beginning with ‘How to become a Christian,’ it answers the questions new Christians most often ask: -​

  • Can we know that we are saved?
  • What is God like?
  • Why we act the way we do.
  • Can I really be set free?
  • Is Jesus God?
  • Which is the right Church?
  • And much more.​

The ‘stand-alone’ studies are linked into a series with each lesson building on the one before.  Important subjects are tackled, yet without losing simplicity, and several question-and-answer systems are employed to provide variety and interest to the end. Over 300 Bible references are used and logically threaded throughout, making River a 100% scripture-based foundation course.

River Discipleship is ideal for individual study. It can be used in other ways too:  Home groups, for sermon notes, as a one-on-one follow-up course.  For more on ‘How to Use’, please download Rock Leaders Manual.

Rock Solid – Advanced Christian Series

Rock Leaders

Rock Solid is a series of advanced studies for home groups and mature Bible students wishing to take their biblical knowledge to the next level. It has the same simple style as the ‘River’ basics course with imaginative diagrams and question-and-answer formats. However, there are some difficult topics. For example: -​

  • Are we under the ten commandments?
  • What is the unforgivable sin?
  • How the world began.
  • Will the world come to an end?

At present, there are thirteen studies in ‘Rock’ each of which may take several sessions to complete. When they touch on what might be deemed controversial, I have presented main viewpoints and suggested open minded discussion. Such open discussion would best suit a group setting, but only if the leader was skilled in presenting a fair overview and treated different viewpoints respectfully.

Rock Solid can be used in other ways too:  Individual study and/or sermon notes.  For more on ‘How to Use’, please download Rock Leaders Manual.

Chronology of the Kingdom

Piecing together the jigsaw of Bible chronology is not an easy task, so claims of pin-point accuracy concerning ancient dates tend to get dismissed. Is it not more reasonable to say, “approximately?” However, the internal chronologies of the Old Testament are more accurate than previously thought, Continue reading

The Atonement Clock – E-pub Edition

Beneath the surface of the Bible lies a timeline of incredible precision.

In 1859 a Jewish scholar, Benedict Zuckermann published a table of sabbatical years in ancient times. He based his conclusions on a variety of sources such as the book of Maccabees and Josephus. In one example he cites an exemption Alexander the Great granted Jews concerning payment of tax every seventh year.

The Fiftieth Year

This brings us to the second synchronisation. In addition to the ‘week’, the Bible reveals a 49-year Sabbatic cycle starting New Year, 1st of Abib, following the previous block of forty-nine. They would have intercalated months as explained using the short cycle, until it reached the 7th month of the 49th year Then on the tenth day, a special 50th year was announced. This might seem strange but another astronomical formula is at work. Continue reading
