Sorry, no, they were saved by grace through faith based on their obedience to the revelation available to them.
But thanks for your opinion.
This is true.
Yeshua1, you have been shown numerous times that this is not the case.
Their sins were forgiven, they did receive atonement...through animal sacrifice.
You are teaching heresy and equating the sacrifice of animals with the Sacrifice of Christ.
Hebrews 10:1-4
King James Version (KJV)
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
4 For it is not possible that the blood of bulls and of goats should take away sins.
Hebrews is specific to the people of Israel, but, the blood (death) of animals offered up by Abel, Noah, and Abraham...
...didn't take their sins, despite their receiving atonement and remission of sins through those sacrifices.
This...
Hebrews 10:14
King James Version (KJV)
14 For by one offering he hath perfected for ever them that are sanctified.
...is the only Sacrifice that can take away sins and the penalty, and make the comer thereunto...perfect.
That is...complete in regards to the subject the Writer is trying to teach you about, which is Remission of sins.
This is the (one) promise of God in the Old Testament...
Jeremiah 31:31-34
King James Version (KJV)
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
Hebrews 10:15-18
King James Version (KJV)
15 Whereof the Holy Ghost also is a witness to us: for after that he had said before,
16 This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
17 And their sins and iniquities will I remember no more.
18 Now where remission of these is, there is no more offering for sin.
Do you understand that when Abel died...men kept offering up sacrifice?
When Noah died...men kept offering up sacrifice?
When Abraham died...men kept offering up sacrifice?
When Christ died...there is no more offering for sacrifice?
Honestly, Yeshua1, this is just basic. You need to let that pulpit mythology go.
So did Remission of Sins on an eternal basis, as shown above.
So did Eternal Redemption, as shown here...
Hebrews 9:12-15
King James Version (KJV)
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
Abraham and David did not receive the promises:
Hebrews 11:13
King James Version (KJV)
13 These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth.
They were not made perfect:
Hebrews 11:39-40
King James Version (KJV)
39 And these all, having obtained a good report through faith, received not the promise:
40 God having provided some better thing for us, that they without us should not be made perfect.
So your statement...
...is grave error, though a common one embraced by many.
God bless.
