Heb 10:3But in those sacrifices there is a remembrance again made of sins every year.Heb 10:4For it is not possible that the blood of bulls and of goats should take away sins.Heb 10:5Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:Heb 10:6In burnt offerings and sacrifices for sin thou hast had no pleasure.Heb 10:7Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.Heb 10:8Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;Heb 10:9Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.Heb 10:10By the which will we are sanctified through the offering of the body of Jesus Christ once for all.Heb 10:11And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:Heb 10:12But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
I am fully aware of what that pauline student wrote , but lets see what the Scriptures say
"And the priest shall make atonement for him with the ram of the trespass-offering before Jehovah for his sin which he hath sinned: and the sin which he hath sinned shall be forgiven him."
"All its fat he shall offer up in smoke on the altar as in the case of the fat of the sacrifice of peace offerings. Thus the priest shall make atonement for him in regard to his sin, and he will be forgiven."
"You forgave the iniquity of Your people; You covered all their sin. Selah."
"I acknowledged my sin unto thee, And mine iniquity did I not hide: I said, I will confess my transgressions unto Jehovah; And thou forgavest the iniquity of my sin. Selah"
""Pardon, I pray, the iniquity of this people according to the greatness of Your lovingkindness, just as You also have forgiven this people, from Egypt even until now.""
"Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy."
"and My people who are called by My name humble themselves and pray and seek My face and turn from their wicked ways, then I will hear from heaven, will forgive their sin and will heal their land."
"But if he be not able to bring two turtledoves, or two young pigeons, then he that sinned shall bring for his offering the tenth part of an ephah of fine flour for a sin offering; he shall put no oil on it, neither shall he put any frankincense thereon: for it is a sin offering.
12 Then shall he bring it to the priest, and the priest shall take his handful of it, even a memorial thereof, and burn it on the altar, according to the offerings made by fire to the LORD: it is a sin offering.
13 And the priest shall make an atonement for him as touching his sin that he has sinned in one of these, and it shall be forgiven him:"
"Let wicked people abandon their ways. Let evil people abandon their thoughts. Let them return to the LORD, and he will show compassion to them. Let them return to our God, because he will freely forgive them."
"Bless the LORD, O my soul, and forget not all his benefits:
3 Who forgiveth all thine iniquities; who healeth all thy diseases;
4 Who redeemeth thy life from destruction; who crowneth thee with lovingkindness and tender mercies;"
"They refused to listen. They forgot the miracles you performed for them. They became stubborn and appointed a leader to take them back to slavery [in Egypt]. But you are a forgiving God, one who is compassionate, merciful, patient, and always ready to forgive. You never abandoned them,"Even when they made for themselves A calf of molten metal And said, 'This is your God Who brought you up from Egypt,' And committed great blasphemies,You, in Your great compassion, Did not forsake them in the wilderness; The pillar of cloud did not leave them by day, To guide them on their way, Nor the pillar of fire by night, to light for them the way in which they were to go."
