In other words, the end of the sinful world is also the hopeful time when the new world of goodness will begin. Since God cannot just leave this world of evil and hell as it is and begin another world of goodness and heaven, a time of judgment, a time of destroying sinful things, must accompany the Last Days.
God has been working with such an aching and anxious heart to restore the world into goodness, so God has always hoped for man to successfully fulfill His providence for the Last Days. However, man repeatedly failed to accomplish his responsibility and thus the Bible records that the Last Days were to occur in Noah's time and in Jesus' time and will again occur at the time of the Second Coming of Christ.
