What does the Bible say about warning others of sin?

In Jeremiah 6:14-17, God commands His people to warn others about their sin and the consequences of remaining in it. This task is echoed in Ezekiel 3:17-19, where the prophet is appointed as a watchman, responsible for alerting the wicked about their ways. The role of the preacher or watchman is not merely to comfort but to confront sin, urging repentance and pointing to Christ as the solution. Without this warning, the spiritual well-being of the community is jeopardized, akin to a shepherd failing to protect the flock from harm.
