The great tribulation is God's harvest time. The book is based on the study of end-time prophecies and how they unfold. It includes what the world will be experiencing in the near future and what the followers of Jesus Christ will be doing during this time. The front cover pictures Armageddon. Jesus Christ suffered the "wrath of God" so that those who put faith in Him and trust Him until the end would not have to suffer God's wrath, but be accounted worthy to escape Armageddon, because of their faith.
