This document discusses the idea of guardian angels and shepherds watching over humans based on several Bible passages. It notes that angels are described in the Bible as being sent to guard and serve people. It also analyzes two parables told by Jesus about a lost sheep, and discusses how they were intended for different audiences. The document ends by drawing three applications about humans both being like wandering sheep in need of care, and having a role in caring for others as shepherds guided by Jesus' example of never giving up on lost sheep.
