GINOLJC, to all.
@Miss Hepburn. the best way to explain this is to take it one step at a time.
Step I, starting at the beginning. Adam and Eve sinned against God, disobeyed. and as a result of their sinning, a separation from God and his benefits. but understand this, there are two types of separation from God in sin, called "DEATHS". see, God is LIFE, and once we separate from God, not him from us, but us from him, we began to DIE, and DEATH is progressive. here are the stages of death. the first separation, or death is physical, or natural death, the progression of the Body, of Flesh and bones, back to dust. from the day we're born we're headed to the graveyard, and it don't take long. this separation results in what we call NATURAL DEATH. Understand, separation, or natural death is immediate, and eventually if not corrected, eternally. which is the second death. yes, there are two deaths. Natural/Physical, and Spiritual/Eternally. as said, natural separation is progressive. in it's progression, one’s time or lengths in that progression is determine by one's change of mind and heart. What I’m saying, one's natural life can be shorten, or extended, (but it have a limit), based on one's actions here on earth. and those actions can be social, or spiritual.
Knowing that, what is the remedy to this first death, and how to avoided the second one?. answer, another death. Just like we’re born again, or born twice. we also die again, twice, (But without the shedding of blood), and or if the Lord Jesus returns before we die naturally. this is why baptism is important (TO THE LIVING, and not the dead), which is a witness.
Now what do this “death” do?, scripture, Romans 5:12 "Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned”. now, Romans 5:14 "Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of
Adam's transgression, who is the figure of him that was to come”. OK, HIM to come. What did he, the Lord Jesus do concerning this thing call death by sin? Answer, Romans 5:15-19 "But not as the offence, so also is the free gift. For if through
the offence of one many be dead, much more the grace of God, and
the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. And not as it was by one that sinned, so is the gift:
for the judgment was by one to condemnation, but
the free gift is of many offences unto justification. For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness
shall reign in life by one, Jesus Christ.) Therefore as
by the offence of one judgment came upon all men to condemnation; even so
by the righteousness of one the free gift came upon all men unto justification of life. For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous”.
Lets sum this up. The one man Jesus die so that we might live. And in his death, out came blood & water. The blood is for a NEW COVENANT, but did I not say it was for the remission of sins that are past, yes, and gave scripture for it? Romans 3:25 "Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness
for the remission of sins that are past, through the forbearance of God”. so how are you saying it’s for the NEW COVENANT. Listen and understand. Matthew 26:28 "For this is
my blood of the new testament, which is shed for many for the remission of sins”. the remission of sins? Which ones? The one’s that are are past,or that was under the old covenant. Scripture, Jeremiah 31:31 "Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah……… now to verse 34b “ for I will forgive their iniquity, and I will remember their sin no more”. this is very important. Forgiveness, and not remembering sin. His death, his blood is the remission, or the forgetting of sin. And his water is for the washing or the forgiveness of the ACTS of the sin. I worded that way for a reason. Understand, sin is a spiritual act, iniquity is a physical act. That’s why the scriptures states, 1 John 3:9 "Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God”. hence the reason that sin was condemned in the the flesh. This condemnation of sin in the flesh is our struggle, not with God, but with ourselves. For sin is finish between God and man, now, the fight or the struggle is on with ourselves. understand, God don't put NEW WINE into OLD BOTTLES, that's why we're sealed with the Holy Spirit of the renewing of one's mind, not one's body, hence the struggle. mind/soul and body. if one live after the flesh, metaphorically speaking your bottle will burst, or one will be LOST/CONDEMNED. scripture, Romans 8:1 "There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. Which leads us to step II, our struggle with ourselves.
since you asked about the blood, it was give once, but now we're under a NEW COVENANT, which is Spiritual.

Peace in Christ Yeshua.
