So you are saying David meant that the condition of his conception was a sin? How so?
It is appears to me that David is expressing his disdain at being born into a world of iniquity.
Some believe he is referring to being born of an illicit relationship but at looking at the whole context of the passage I don't lean in that direction. What we do know is that David is most definitely not teaching that sin was born inside him, not only does he not say that but the Jews never taught it that way.
Inborn sin was never taught in the early church but became cemented into Christian orthodoxy through Bishop Augustine of Hippo. I linked a video above which discusses this very issue and I encourage you to take the time and watch it.
We do not inherit the guilt of Adam's sin nor is the sin imputed on us (we didn't eat the forbidden fruit) rather all are born with the tendency to sin because by him sin came into the world. Do you need to sit down and teach a child to steal other kids' toys, lie, or disobey their parents before they start those? No. Why? Because of the carnal and depraved nature of man. Proverbs 22:15-Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him. Who teaches that child foolish behaviors?
The tendency to sin is simply the natural passions and desires of the flesh. These existed PRIOR to Adam and Eve's first sin. Eve was enticed by the lust of her flesh and she freely chose to yield to those desires in disobedience to God.
Gen 3:6 And when the woman
saw that the tree was good for food, and that it was
pleasant to the eyes, and a tree to be
desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
James describes this process very clearly.
Jas 1:13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
Jas 1:14 But
every man is tempted, when he is drawn away of his own lust, and enticed.
Jas 1:15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
Conceived lust brings forth sin because it is freely yielded to in the mind. God told Cain that he should rule over the desire to sin...
Gen 4:6 And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?
Gen 4:7 If thou doest well, shalt thou not be accepted? and if thou doest not well,
sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
Sin is rooted in the free choice that men make to yield to their fleshly desires in disobedience to God. Sin is not the result of some evil inborn nature passed down from Adam. That is an erroneous teaching upon which much false doctrine has been established.
Adam was created innocent and so is a baby. Adam walked with God but did not have the holy spirit within just like a baby.
When people sin they sell themselves into bondage and that is when a sin nature begins to develop, this sin nature becomes more entrenched over time through the long practiced habit of sinning because sin hardens the heart. The light of God must be suppressed in the mind in order to commit sin and the end of such action is eventually a reprobate with a seared conscience.
I understand that there is also a nurture aspect.
If everyone is born without a sinful nature, why was death passed upon all men? Why does the bible say all (inclusive) have sinned? There is no exception. Like I said before children are not held accountable for their sins until they reach the age where they can discern right from wrong, so essentially they are innocent in God's sight. No wonder why Jesus said in Luke 18:16 " ...Suffer little children to come unto me, and forbid them not: for of such is the kingdom of God". The age of accountability is between God and that individual.
Death was passed upon all men because all have sinned. All men have followed in the likeness of Adam's action and have gone their own way in disregard to the instruction of God, whether they violated their conscience (Joh 1:9, Jam 4:17) or a direct command of God (1Joh 3:4).
A child is not held accountable when they are young because they cannot sin. Sin can only take occasion by the law and then it brings death.
Rom 7:8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
Rom 7:9 For I was alive without the law once: but when the commandment came, sin revived, and I died.
Rom 7:10 And the commandment, which was ordained to life, I found to be unto death.
Paul was speaking in the context of the moral law of Moses but the same principle applies for those who violate their conscience.
Rom 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.
Sins unto death are those which are rooted in willful transgression.
Summing up.
The doctrine of original sin is a heretical teaching which completely redefines the Gospel because it redefines sin from being the result of the free independent choices of men and puts the blame on tha state in which one was born.
Thus repentance is redefined into a concept of "confessing a sinful condition."
Due to the adherent of the doctrine believing that they were born sinful and thus actual sin is simply necessitated by this condition they then believe they cannot forsake all sin. Thus repentance is neutralised in the mind and reconciliation to God through genuine repentance and faith is thwarted.
Today we have a world of professing Christianity (a whore that rides the beast) that believes that sin is inevitable and thus they hold to a theology which teaches that they get saved IN their sins. The sin and rebellion never stops and thus they are cloaked in a fake provision of Jesus while they continue to serve two masters, remain double minded, carnal and sold under sin, as they wait for God to clean them up some time down the road.
These people never realise that the initial cleanup is meant to occur in the process of repentance, where they are broken on the rock of Christ whereby all willful rebellion is purged from the heart, which then puts them in a position where they will yield to the leading of God and thus be purified by the implanted word within.
Even after we are saved, That is why we are lucky to have a merciful God, and the guidance of the Holy spirit
