I notice a host of articles and book titles about Self Improvement. They generally assume that faith is irrelevant, as if those ancient concepts of sin, grace and atonement are irrelevant. Or, some would say, harmful.
I believe Jesus teaches us a great deal about self-improvement, but that you have to stop trying!! A point totally missed by Philip Pullman’s Magisterium in His Dark Materials. Have a read and see what you think!
