The wall of bricks during Lent is a visual symbol of the nebulous walls that we create when we stop connecting with God and with one another… when we start turning ourselves inward. Walter Brueggemann, author of our Lenten study Sabbath as Resistance, talks about living in a world at "brick making speed" when we are always producing and always in this productivity mode and we don't take time to rest, which prevents us from being the neighbors that God calls us to be. So the wall was built up as a visual representation of what it looks like when walls begin to prevent us from doing the things we would normally do… such as worship in a regular way.
