At the point in your life when you look at God, place faith alone in Christ alone, God is free to regenerate your human spirit. Immediately, you then have a body, a soul, and human spirit which is also sealed by the Holy Spirit.
No matter what you do from then on out, you cannot lose your eternal life, because God foreknew you.
In regards to forgiveness of sin, all your pre-salvation sins are all forgiven at the moment of salvation. Post salvation sin is forgiven at the moment of turning back to God, and confessing known and unknown sins to Him via 1st John 1:9.
With respect to God, Christ paid for all sins, past, present, and future while He was on the Cross.
Our Lord and Savior Christ Jesus agreed in eternity past to perform 4 things at the Cross.
1) Unlimited substitutionary atonement for all sin throughout all of humanity.
2) Propitiation of sin, where His work towards sin resulted in all sin being covered by His blood, the perfect sacrifice, thereby covering all wrath of God in His perfect righteousness which demanded perfect justice upon all sin.
3) Redemption, or buying the debt all man owed God for having broken a relationship with God in the Garden of Eden and for all sin in the future generically, which was no fault of God.
4) Reconciliation of Man to God. God is never reconciled to man, rather man who is the creature and who sinned in the Garden of Eden produced actions which effected a barrier between God in His Perfect Righteousness and man who had missed the mark and had disobeyed God, thereby becoming unrighteous. That barrier was removed by Christ on the cross in His love for all mankind and God’s perfect Judgment of all sin in Him, in His body.
At the Cross, Christ in his humanity, empowered by God the Holy Spirit, remained in faith with Him in all things,...again in his humanity (see doctrines of kenosis)
After having all of mankind’s sins imputed upon him, past, present and future sin, our Lord and Savior was Judged on the Cross.
The Gospels well record the events, especially in Luke 23:44. The forgiveness of Christ to those who crucified Him, was a prayer to God the Father to Forgive them as a personal request for what they did to his body personally, not to be confused with the forgiveness of all personal sin of all humanity.
After three hours of judgment from about 3pm to 6pm, with an earthquake, our Lord and Savior cried out, Eli, Eli, lama sabachathani, (My God, My God, Why have You Foresaken Me!)(Mark 15:34) This well reflects a spiritual death of the human Jesus on the Cross. The penalty of sin is death. Adam and the second Adam had life in body, soul, and spirit. Death is a state of existence involving separation. At this point our Lord had been separated from God the Father in His humanity, it was a spiritual death. This was indubitably the most violent of all events in human history. Violent in that it crossed the willpower and volition of our Lord and Savior Christ Jesus. He did not want to be separated from the Father, but in his human spirit, took on all the sins of the world, past present and future, thereby being judged by God the Father for us because of His love for us. At this point in time he still had a living soul, he also had a living body, albeit battered and in stress physically.
When some heard his comment, they confused it for the Prophecy by Elijah, and mistook him for quotng Elijah. Please note, our Lord has primacy in this Prophecy, not Elijah. Some around him ran to get him something to drink. A sour wine or vinegar which had a narcotic effect on the body which was commonly used as a cheap drug for those being crucified.
At this point our Lord and Savior had soul and body, but had suffered spiritual death.
Matthew and Mark then records our Lord let out a shout then gave up the Ghost, with the veil in the temple separating the Holy of Holies from the Holy Place being rent in two.
John records the shout as “It Is Finished! (a tense in the Greek language which means a sense of completeness, finished and forever accomplished).
It might also be noted that as our Lord thrust his head out after he gave up his last breath, the action took volition as the body tends to hang the head to one side or another in the state of crucifixion. The result of this physical position as studied by some medical practitioners results in the blood of the body accumulating in the lower cavities and after death, the blood begins to separate into serum and white blood cells. The appearance of this mixture when released from the body is as red blood and water. Had his head drooped to the side, the blood would have dropped more to the lower extremities of the body. When our Lord’s side was pierced by the guard to affrim his death, blood and water is recorded as being released.
What happened from this point was that the Lord’s human spirit as a man was released to God the Father. The body was later taken to the rich man’s tomb with a large stone rolled in front of it sealing it and guarded by Roman soldiers. The soul of our Lord and Savior Christ Jesus then descended to Hades, specifically to Paradise as documented on the Cross when our Lord told the believing thief He would see him in Paradise , also known as Abraham’s Bosom.
He is also recorded as witnessing to the spirits in prison in 1stPeter 3:18 and in Acts 2:31 we are told His soul was not left in Hades, nor his flesh see corruption.
Hades has four compartments, Paradise or Abraham’s Bosom, separated from the rest by a great gulf transfixed, then the Torments (where souls of the unbelieving reside until Judgment Day), Tartarus (Where fallen angels and some creatures mentioned in Genesis 6, 1stPeter 3:19 and Jude 6, and the Abyss (where Abaddon resides until the middle of the Great Tribulation).
Our Lord though had the power and authority to receive his life again. God the Father in His omnipotence gave the human spirit back to our Lord Christ Jesus and God the Holy Spirit returned the soul to his body, which was a ressurection body incorruptible, the first fruits.
Three days later, our Lord rose again in his body, with soul and spirit in his humanity. Also, at his time at least 40 other saints were ressurrected and he sojourned here on Earth until the Ascension, some forty days later.
Today, God is now free to forgive us our sins when we turn to Him. When he finds something righteous in us, He is free to bestow a regenerated life in us. Rom 3:20-24 indicates the righteousness of God is in and of Christ, indicating when we ourselves exercise faith alone in Christ alone, we also have something He has already recognized as righteous, namely faith in Christ.
So again, forgiveness occurs upon saving faith for pre-salvation sin and at repentance and confession of sin for postsalvation sin per 1st John 1:9.
I agree with you, but there are people that were saved, go bad, don't repent again ever and turn their back to God.
Can't say that is a road to heaven by any means.
I think people can turn their back to God and lose their salvation, kind of like Cain with Able.
