This document is a sermon about sins of omission from a church service at the Jackson Street Church of Christ. It discusses various "un-" sins that Christians should resolve not to commit in the new year, such as being unthankful, unholy, unloving, unfaithful, unfruitful, unaware, unclean, or ungodly. The sermon examines verses from the Bible about each of these sins and encourages Christians to faithfully follow God's commands through both their actions and lack of actions.
