We must remember that the second coming of Jesus Christ is to finally destroy the Evil in what is the Battle of Armageddon and to establish a kingdom out of the redeemed people of God in Earth with Christ himself as the King. It will be the New Earth where the glory of God provides everything for the people. There will be great joy, peace, harmony, and love forever reigns in the hearts of everyone.
"As it was in the days of Noah, so it will be at the coming of the Son of Man", said the Holy Bible in Matthew chapter 24 verse 37. In Noah's time God cleansed the whole of the world with water but in Christ's coming the world shall be cleansed with fire, purifying everything, element after element. The old world must be destroyed for the new one to take place.
Is the world coming to an end soon? The Bible clearly tells us about it in Matthew 24:36-39: "No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. 37 As it was in the days of Noah, so it will be at the coming of the Son of Man. 38 For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39 and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man."
