Every Christian has been appointed as a watchman. When we are watchmen, it is our responsibility to warn the people of the coming judgment. We can’t make them heed the warning - we are not called to force them to change, but we are called to alert them. It is an eternal life and death situation for both the watchmen and for the lost.
Scriptures used: Isaiah 62:6-9, Ezekiel 33:1-9, Jeremiah 1:13-17, John 6:66-69
