Every human since first Adam has sin living in our natural body, that sin is counted to the soul which lives forever after the body of flesh dies.
God is ferect and does not allow sin, to save every soul from having to get locked out of heaven after they die, God sent His only Begotten Son Jesus who was born into a body of flesh but without sin in his body because He only had one human parent, His genetic coding was perfected by the codex called Word of God by which life was initiated in the 'seed of the woman' this devine plan of God for salvation was foretold in Genesis 3:15

Today we are saved from eternal damnation by trusting the gospel of our salvation and nothing else, we do not have to work or do actions to be accepted by God the Father only to trust the
following gospel given by Jesus to Paul:1 Corinthians 15:1-41 Moreover, brethren, I declare unto you
the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are
saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received,
how that Christ died for our sins according to the scriptures;4 And that
He was buried, and that He rose again the third day according to the scriptures.The second we trust this gospel, God the Father revives our dead spirit - we are born again of the Spirit, our soul is washed clean of any guilt of sin by the shed blood sacrifice of Jesus that is
applied to our personal soul the second we trust the gospel. Then we receive a spiritual cutting off - circumcision of our sin in the flesh from the new creature in us that is our soul+spirit+Holy Spirit, the new born creature can not sin because it is of the Spirit, the sins of the flesh are not accounted unto our soul. When we leave our body we have a place in heaven, and we have no fear of a coming punishment because Love that had been perfected in Jesus' sacrifice for us cast out all fear of being punished by God - 1 John 4:18.
Before the end of our era of grace, we are still being saved by trusting the blood atonement of Jesus the lamb ordained by God for the remission of all sins to all who trust the blood of Jesus that was shed for our eternal salvation.
This dispensation of salvation (by the grace of God and faith alone in Jesus blood atonement, and resurrection for our justification) is about to close.
Jesus Christ is foretold to be returning after 2 days on the 3rd day, and 1 day is a 1000 years with the Lord, Jesus resurrected from the dead and was seen in His spiritual supernatural body by His desciples, and then was taken up to heaven, as Enoch was taken up to heaven.
Jesus will come back to take His body that is His believing body of born again spiritual beings that we become when we believe the gospel.
We shall be like Him when He comes - He is light.
After our dispensation of salvation by God's grace and us simply believing God for what He did, will come a dispensation of having to work very hard for your salvation, the tribulation era.
You can be saved today simply by trusting the gospel.
