Heb 9:22 - Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.

@Dottard - I completely agree. What I am looking for is if scripture can equate a solution for what looks like an imbalance. If physical death = 1, and spiritual death = 2, then physical death minus spiritual death = minus 1. Math being used as an analogy. My question is saying that spiritual death is an overkill for physical death. If the wages of sin is death including both spiritual and physical, then how can merely the physical death of Jesus atone for both?

I wonder if there's a precedent about a human sacrifice to atone for the sins of others. It is written that sons will not be punished for the sins of their father, so, seemingly Jesus dying to atone for the sins of others contradicts that.

@Biff – Is it possible to provide a Scriptural reference to ‘spiritual death’? I searched but couldn’t find one.

@Nephsh - Have you ever heard of the 2nd death?

This question seems to be based on "If sin causes spiritual death". Is that a hypothetical question, or the doctrine of some specific denominations, or is there biblical text that states this?

@NepheshRoi, it's easy to look up. Spiritual death is common vernacular to describe the dead state Paul ascribes to people who were physically living at the time the state is ascribed to them in Eph 2:1 & Col 2:13 "...you were dead in your transgressions and sins..."

Hi @RayButterworth, please see comment to NepheshRoi.

@Ray B. - A physical death is the separation of the soul from the body. Spiritual death is the separation of the soul from God. Scripture is filled with examples of being separated from God. This is why when Jesus is on the cross he says "My God, my God why have you forsaken me", showing the separation that has occurred due to Him becoming sin. Ephesians has a lot to say. Eph 2:1 And you He made alive, who were dead in trespasses and sins. Of course this is not physical death, it is referring to the soul due to the wages of sin.

@Biff believes that: "A physical death is the separation of the soul from the body." — What you are saying is not from the Bible, which says that the soul is the body. We should be using exegesis on this site; eisegesis belongs on Christianity.SE.

@Austin, Ephesians 2:1 says that you were effectively dead (i.e. condemned to death) because of sin. There is nothing there referring to "spiritual death"; you are importing that term from somewhere other than the Bible. If it isn't Biblical, it should be in Christianity.SE, not on this site.

@RayButterworth, I already admitted it was common vernacular and thus not strictly Biblical. Common ways of referring to scriptural concepts are in no way prohibited on this site, though I agree it would be more efficient to use strictly Biblical terminology. "Ephesians 2:1 says that you were effectively dead (i.e. condemned to death)" Now you are the one saying what Ephesians 2:1 doesn't actually say by substituting your own interpretation. I don't mean to argue. Thanks for giving your opinion and clarifying your interpretation.

@RayButterworth - " What you are saying is not from the Bible, which says that the soul is the body. " Ray, I cannot find this in scripture. Can you provide a ref. please? 1 Thess 5:23 - Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ. Paul seems to disagree with your last statement making a clear distinction between your triune image of God.

@Biff: "I cannot find this in scripture" — Numbers 19:13: "Whosoever toucheth the dead body[nephesh] of any man". The word "body" is translated from the Hebrew "nephesh", which is the same word that is translated as "soul" elsewhere. Is that translation wrong; should it really say "the dead soul of any man"? Genesis 2:7: "man became a living soul[nephesh]". 1 Corinthians: "Adam was made a living soul". Genesis 1:24: "Let the earth bring forth the living creature[nephesh] after his kind, cattle, and creeping thing, and beast …". You are using English "soul" with its Pagan meaning.

@RayButterworth Thanks Ray I'll check it out

@Biff – The second death is physical when the entire person (both soul and body) is destroyed in Gehenna Fire (Mat 10:28). The Scripture doesn’t say it is spiritual death.

@Austin – I understood your point. But here is the logic. Physical death comes after physical life. So, if these unbelievers were spiritually dead, the question is: when were they spiritually alive so that they can die spiritually?

@NepheshRoi, babies aren't condemned to die eternally. The relationship with God remains intact. As Paul says your sin after awareness of the law kills.

@Austin – I agree, babies are not condemned to die eternally. But that doesn’t mean they are automatically saved either. Paul tells Timothy: “and that from a babe you know the Holy Scriptures, those being able to make you wise to salvation through belief in Christ Jesus” (2 Tim 3:15). Babies or adults, salvation is only through belief in Jesus Christ!

@Austin – not condemned doesn’t mean that one is automatically saved either. One needs to come to “the full knowledge of the Son of God, to a full-grown man, to the measure of the stature of the fullness of Christ” (Eph 4:13). Figures of speech or hyperbole, Apostle Paul doesn’t speak highly of babies! Eph 4:13 continues: “so that we may no longer be infants” (verse 14)! “For everyone who lives on milk is still a baby and does not yet know the difference between right and wrong” (Heb 5:13).

“And I, brothers, was not able to speak to you as to spiritual, but as to fleshly — as to babies in Christ; with milk I fed you, and not with meat, for you were not yet able, but not even yet are you now able, for yet you are fleshly” (1 Cor 3:1-3).
