Why is the concept of watchmen important for Christians?

In the Christian context, the metaphor of watchmen serves to illustrate the responsibility believers have to care for the souls around them. Just as watchmen alert travelers to dangers ahead, Christians are called to declare the truth of the Gospel and warn others of the perils of sin and disobedience. Newton expresses the emotional toll this can take, highlighting the rejection that Gospel ministers often face, akin to the treatment of prophets in Scripture. The critical importance of being a watchman lies in the urgency of the message: to guide others toward the salvation offered through Jesus Christ, encouraging them to cross the bridge of faith before it's too late.
