Through sin, death came into Creation.
Yes, you are born into sin, even if you are a baby and still did not sin.
Your human body is one of corruption and death.
It was sin that changed Adam and Eve's bodies from being immortal, to the one we hace now, a mortal body.
Every second that ticks away, we age, and cells in our bodies dies.
We are nothing than living corpses.
Unlike the bodies which was occupied by Adam and Eve that did not age before they sinned.
and this was why Satan deceived them into sinning against God.
To remove God's friend He created for Him because no corruption can be in the presence of His Glory.
This was why Jesus came to be made the sinoffering of us all, to have His blood cover our Sinfull nature just as the High Priest of ancient times had to sacrifice and cover the sins of Israel with Blood.
There is a special atribute about Blood in the face of God.
Blood covers the corrupted bodies we have to protect us from being destroyed in His presence.
Think about this,
Jesus was born as a human, therefore in a corrupt body like us, and He aged like us, and He died like us.
however, he rose from the dead after his blood was spilled, and had a body with no blood, for he told Thomas, He was not a ghost, for a ghost do not have flesh and bone.
Jesus was also very clear when he said, no flesh and blood will enter heaven.
therefore, Adam and Eve were clothed in a bright covering of light, but they lost their immortality when they sinned, and lost this light, which was replaced by blood, but they now had a body of flesh, bone and blood.
Jesus was killed with the same body of Bone, flesh and blood, but He changed into an immortal body of Flesh and bone only, and the blood remained here on earth. he again obtained the light which Adam and Eve were clothed with.
Yes, I was born in sin, because of my corrupt body, even though I still did not commit any sin.
This is the gospel, that Jesus came to change our sinfull nature, eg bodies, to be able to live forever.
It is up to us to change our sinfull mind. That is our choice.
