"The next point I wish to consider is the process by which the world shall pass away. Of that first world we read, “The world that then was, being overflowed with water, perished: but the heavens and the earth which are now, by the same word are kept in store, reserved unto fire” (II Pet. 3:6-7). The fact that the water which destroyed that first world was literal leads some to believe that the fire which shall destroy this present world must also be literal — but this by no means follows. The temple of God once was of literal stones, but that does not set aside the fact that the body of Christ, which is now the true temple, is built up a spiritual building, a holy temple, not made with hands. Noah’s ark was literal too, but it typified Christ who is now our hiding place and the mighty resurrection power of Him who will save the sons of God from the loss of this perishing world and which, through them, shall replenish and renew humanity. Almost all things under the old covenant were outward, natural, and literal; almost all things under the new covenant are inward, spiritual, and supernatural! Think of it!"
