The Answerer

Well the whole world will not ‘disappear’ as you say. Jesus said it would be : "...the end of the age.” Not the world. What will happen is that the earth will be cleaned up, I think by fire, and all evil will be removed and replaced by God’s new heaven and new earth. To go into detail would take many pages, too heavy for a child to digest. Be assured: If you are a part of God’s family you will be very pleased when it all happens and have no worries at all. May God bless your future.
