How are personals sins atoned and accounted for then if not PST?
Ransom is the way, we are redeemed by a ransom paid for our sins. But not paid to Satan that thinking is an error, it is paid to God, the Law of God which required the blood to be shed for the forgiveness of sin. God Himself bore our sins on the Tree, the Tree which He Himself required for our sins, that is such a great love manifested towards us. He required His own death of Himself for us to live towards God.
God the Son paid the ransom back to Himself God the Father. Satan had no part in this.
Otherwise, we would suffer the wrath of God for our sins which are many.
And Christ delivers us from the wrath of God to come.
Isaiah 35:10
And the ransomed of the Lord shall return, And come to Zion with singing, With everlasting joy on their heads. They shall obtain joy and gladness, And sorrow and sighing shall flee away.
Jeremiah 31:11
For the Lord has redeemed Jacob, And ransomed him from the hand of one stronger than he.
Hosea 13:14
“I will ransom them from the power of the grave; I will redeem them from death. O Death, I will be your plagues! O Grave, I will be your destruction! Pity is hidden from My eyes.”
Matthew 20:28
just as the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.”
Mark 10:45
For even the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.” (not all)
1 Timothy 2:6
who gave Himself a ransom for all, to be testified in due time, (not all who have ever lived)
Christ was give Himself a ransom for them who are saved, not that Christ ransomed all people, if so then all people would be redeemed..Christ bore the sins of many...Many are the great host of the redeemed who are named in the family of God in heaven and earth.
Isaiah 53
10 Yet it pleased the Lord to bruise Him;
He has put Him to grief.
When You make His soul an offering for sin,
He shall see His seed, He shall prolong His days,
And the pleasure of the Lord shall prosper in His hand.
11 He shall see the labor of His soul, and be satisfied.
By His knowledge My righteous Servant shall justify many,
For He shall bear their iniquities.
12 Therefore I will divide Him a portion with the great,
And He shall divide the spoil with the strong,
Because He poured out His soul unto death,
And He was numbered with the transgressors,
And He bore the sin of many,
And made intercession for the transgressors.
