Well I guess I'll help you out. there are two deaths. only one you cannot come back from.
there is the natural death, meaning loss of blood. for the blood is the "LIFE" of the body, supportive scripture, Leviticus 17:11 "For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the sou"l.
now the second death. Revelation 20:14 "And death and hell were cast into the lake of fire. This is the second death". so the bible clearly speak of two deaths.
Revelation 21:7 & 8 "He that overcometh shall inherit all things; and I will be his God, and he shall be my son. 8 "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death".
