The Lake of Theos is experienced by the radical all of mankind to finish what has not been "hurt" of the old man nature.
except
Those who follow the Lamb in the withersoever, (described as overcomers).
Overcomers ALONE are NOT hurt by the 2nd death, (aka Lake of Theos).
Those that follow the Lamb cannot be "hurt" by the Lake because there is nothing left to hurt,
They have been hurt over and over and over again.
There is nothing left to hurt!
God will not look you over for medals, degrees or diplomas but for scars. ~Elbert Hubbard
