God has designed our world to be shaped by seasons: Spring, Summer, Fall, and Winter. Our lives are also shaped by seasons - made up of times of abundance, joy, and celebration, as well as times of suffering, pain, and loss.
This is why our calendars are filled with holidays, literally meaning holy days. These are days set apart from all the rest. We mark the days that have marked us. These holidays remind us every season of who we are, where we have been, and who we desire to be. So too with the Church calendar. Followers of Jesus have designed and followed the Church calendar to mark their lives and days by the arrival, life, death, resurrection, ascension, and return of Christ.
Beginning on Ash Wednesday, for forty days during Lent, we strip away some of our usual comforts (often through fasting) to create more space for reflection, repentance, and refining. These days ready our hearts to gaze upon the gore of Good Friday, and the glory of Resurrection Sunday.
