Dr James Engel developed a model, known as the ‘Engel Scale’, that’s helpful in describing evangelism as the process leading towards a decision. Imagine a line or a scale with zero at the centre, and minus numbers to the left (–1, –3, –10 etc.) and positive numbers to the right A person who is asking questions and seeking God could be said to be a –1, but someone who wants to knock your block off rather than hear the gospel they’re a –10! Believers are all on the plus side… as we continue to grow and mature in faith we move along the line (+1, +4, +10, etc.). If you move a person from say, –5 to –3, is that not part of the evangelism process? You may not be there for the “zero hour”, but God has certainly used you in the process.
