Assuming that there is an 'original sin' from the 'times of Adam and Eve' is it inherited, is there a gene to determine if you get the O.S.? Has it been changed by evolution? Can it be genetically bred out of us so as to skip judegement and head right on ahead to heaven?
Sin that started with Adam causes death.
Once Adam sinned he became imperfect in mind and body.
We being born imperfect can sin by mistake or because of Adamic sin.
If one could stop sinning one would not die.
If sin could be bred out of us we would not need Jesus as Mediator or Messiah or Ransomer or Savior.
The sheep-like righteous ones of Matthew chapter 25 are alive or living at the time that Jesus, through divine intervention, takes action into mankind's affairs. They do not head off to heaven. Please notice in verse 46 that the living righteous ones are on earth remaining alive into everlasting life.
They are alive on earth and remain alive on earth when they start gaining eternal life right here on earth during Jesus 1000-year reign over earth. -Proverbs 2:21,22.
They will not be alone on earth, or the only ones that will live on earth.
Jesus said he had a little flock at Luke 12:32 and this righteous little group will rule with Jesus in the heavens -Rev 5:9,10, but the other sheep of John 10:16 will reside on earth as earthly subjects of God's kingdom by Christ.
These will include resurrected ones back to earth such as the prophet Daniel looked forward (12:2,13), and Job (14:13-15) looked forward to the appointed time until the resurrection on the last day or Jesus righteous judgment day of one-thousand years in length. -Acts 24:15; John 11:24.
If Adam had not disobeyed or sinned Adam would have remained a perfect human in healthy mind and body. God's original purpose was to have the earth populated with perfectly healthy people that would remain right here on earth forever. God has not abandoned his purpose for the earth. That is why Jesus could promise that the humble mild-tempered or meek will inherit the earth. Psalm 37:11,29,38 not only mentions the meek inheriting the earth, but verse 29 says it will last forever. So in order for the upright to remain (Prov 2:21) they will have to obtain or gain the same healthy human perfection of mind and body which Adam was originally created. That would require the removal of sickness (Isaiah 33:24) and removal of death (Rev 21:4,5; 1 Cor 15:26) Only Jesus can save us from death, and Jesus will act as Savior during his coming millennium-long day when he ushers in Peace on Earth toward men of goodwill.
