Before Jesus died (in which He sealed His covenant and made it unchangeable) He was able to forgive sin for whatever act of faith He chose to accept, and there are many examples of this. But after His death, there is only one way to receive forgiveness of sin, and that is through obedience to His commands. Just repenting does not bring about forgiveness. Forgiveness is received through the surrender of baptism as is stated explicitly in Rom 6:1-7 and Col 2:11-14. All the people saved by Jesus before His death were saved under the Old Covenant.
One must understand forgiveness of sins in relation to the atonement for sin.

Hebrews 1:3-And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power. When He had made purification of sins, He sat down at the right hand of the Majesty on high;
Purification for sin is in the blood of Christ in the Atonement
Matthew 26:26-29
While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; this is my body.”27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28
This is my blood of the covenant, which is poured out for many for the forgiveness of sins.29 I tell you, I will not drink from this fruit of the vine from now on until that day when I drink it new with you in my Father’s kingdom.”
Hebrews 9:22
Because all things are purged by blood in The Written Law, and
without the shedding of blood there is no forgiveness.
Leviticus 4:20,26,35
And he shall do with the bullock as he did with the bullock for
a sin offering, so shall he do with this: and the priest shall make an
atonement for them, and it shall be forgiven them
Leviticus 6:7
And the priest shall make an
atonement for him before the LORD: and it shall be forgiven him for any thing of all that he hath done in trespassing therein.
Leviticus 17:11
For the life of the flesh is in
the blood, and I have given it to you to make
atonement for your souls upon the altar; for it is
the blood that makes atonement for the soul.
Hebrews 9
Now the first covenant had regulations for worship and also an earthly sanctuary. 2 A tabernacle was set up. In its first room were the lampstand and the table with its consecrated bread; this was called the Holy Place. 3 Behind the second curtain was a room called the Most Holy Place, 4 which had the golden altar of incense and the gold-covered ark of the covenant. This ark contained the gold jar of manna, Aaron’s staff that had budded, and the stone tablets of the covenant. 5 Above the ark were the cherubim of the Glory, overshadowing the atonement cover. But we cannot discuss these things in detail now. 6 When everything had been arranged like this, the priests entered regularly into the outer room to carry on their ministry. 7 But only the high priest entered the inner room, and that only once a year,
and never without blood, which he offered for himself and for the sins the people had committed in ignorance. 8 The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still functioning. 9 This is an illustration for the present time, indicating that the gifts and sacrifices being offered were not able to clear the conscience of the worshiper. 10 They are only a matter of food and drink and various ceremonial washings—external regulations applying until the time of the new order.
The forgiveness of sins is found only in
the blood of Christ- His life which He gave as a sacrifice for sin. That is the heart of
the Atonement. It is what the New Covenant is found upon His blood, His life which was given for our sins. Forgiveness is only found in His blood that He gave His life on our behalf. That is how are sins are removed and taken away. That is what the Law required for sin was the blood of the animal sacrifice.
There is
no "punishment" above anywhere. There is a sacrifice provided which covers and provides forgiveness of sins. The entire book of Hebrews is built upon the OT Law and how it is fulfilled in Christ.

Romans 3:25
God presented Christ as a
sacrifice of atonement, through the shedding of his blood—
to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished. NIV
Romans 3:25
whom God put forward as
a propitiation by his blood
, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins. ESV
The Atonement is received by faith. The offering of the Atonement for sin cannot be obtained apart from faith. The atonement for sin has been made and it cannot be applied to mankind apart from faith. Jesus has made an atonement for sin but it produces no reconciliation, no pardon from sin, no remission of sin unless is accepted or received by faith.
hope this helps !!!
