Life is filled with warnings. Various household products have warnings on their labels. We constantly have traffic warnings and weather warnings. Life would be dangerous indeed if we were never alerted to danger. It is not surprising, therefore, that the Bible contains very specific warnings. This is especially true in the books of Joel and Amos. Joel sounds the trumpet, and Amos roars like lion. Both are designed to alert us to the dangers ahead. This commentary is offered to help you understand the warnings of God and recognize when it is time to sound the alarm.
