Jesus was often on the road. Apart from being, literally, outdoors for a lot of his ministry, the road, or 'the way' was a metaphor for going in a certain direction in his life, going God's way, being open to fellow travellers and averse to settling in one place, for the sake of the kingdom. Eventually his road narrowed and turned towards death - on the road to Jerusalem.
Others joined him on the road, like blind Bartimaeus and the women and other disciples who followed him; and now we're on the road that is called Holy Week, seeking to walk the way of the cross with him, as far as we are able.
Literary tropes of the road include Jack Kerouac's On the Road (1957), a book simultaneously about a literal journey across America and a journey of personal self discovery outside of the mainstream, via jazz, poetry and drug use.
An even more depressing tale is Cormac McCarthy's The Road (2006), a post -apocalyptic story of a father and son travelling on the road through ecologically devastated countryside, trying to reach the sea with a few meagre possessions and a father's terrible burden of protecting a hungry child.
Whether narrow or wide, smooth or full of potholes, going towards death or towards safety, travelled alone or in company, a road always stretches out ahead, and it must be walked.
