Although God declared water would never again destroy the earth, as happened by the flood of Noah’s day, at the end of the age it will be destroyed by fire (Gen 9:11; 2 Pet 3:3-7,10-12). It is unclear whether it is the sun scorching people or the (limited) power of man’s nuclear weapons starting the events at the climax of the world’s history (Rev 16:8,9). This, though, will be nothing compared to the totally encompassing and eternal wrath of God displayed in fire on all those who refuse His mercy (Rev 19:20, 20:10-15, 21:8). Is my security in God (Ps 46:1-3)?
