'It is true that temptation given into is harder to combat next time, but temptation resisted does not necessarily mean that things become easier next time: it may simply mean that we become exposed to a stronger degree of temptation than before. That is how, I think, we should assess the true magnitude of Jesus' achievement. I used to think that because he never sinned, it must somehow have been easier for him. I now appreciate that whereas I never get the full blast of temptation - I fall before it gets that far - he did face that without yielding and he did so time after time. The rope that stands the test of repeated jolts is stronger than one which parts under the strain.'
Michael Green, I Believe in Satan's Downfall, p.62.
