I have a suspicion that the speed of change in our hi-tech world will likely prove faster than Forsyth or Jung could ever have imagined. Jung knew nothing of blogging or twitter. Forsyth could not have envisioned in his darkest nightmares the advent of virtual churches, detached from any bodily contact at all and able to export exegesis, good, bad and indifferent, to anywhere at the touch of a button. Ideas can now move from a classroom to a worldwide audience in an instant. There is also no golden rule which says someone who fought for the gospel at age twenty might not be assuming it at age thirty and abandoning it at age forty. I believe in the perseverance of the saints; but I have been around long enough to know that there are a good many convincing counterfeits out there and, indeed, for myself, that a man should take heed if he thinks he stands lest he fall.
