The first week of Advent begins a new Christian year. If it has been difficult to find hope in 2017, listen to this homily, which highlights the differences between hope and optimism. In this homily, Pastor Caleb looks at a tough passage from Mark 13 about the "day of the Lord." As we prepare for Christmas, Advent encourages us to not only look back at the birth of Christ, but also forward to Christ's coming. Caleb argues on behalf of hope, even when optimism is unlikely.
