Rowan Williams says the following about Lent:
It’s important to remember that the word ‘Lent’ itself comes from the old English word for ‘spring’. It’s not about feeling gloomy for forty days; it’s not about making yourself miserable for forty days; it’s not even about giving things up for forty days. Lent is springtime. It’s preparing for that great climax of springtime which is Easter – new life bursting through death. And as we prepare ourselves for Easter during these days, by prayer and by self-denial, what motivates us and what fills the horizon is not self-denial as an end in itself but trying to sweep and clean the room of our own minds and hearts so that the new life really may have room to come in and take over and transform us at Easter.
