I agree with everyone that no man has ever, or will ever keep the law perfectly. Nevertheless, IF a men were to perfectly keep the law from the moment he is born until he dies he would not be lost and need no repentance. There is no penalty for doing good, the wages of SIN is death.
Jesus was not lying when he said "If ye would enter life, keep the commandments". Jesus was telling the lawyer the truth when he said "Thou hast answered correctly, this do, and live"
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
Luk 10:25 And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life?
26 He said unto him, What is written in the law? how readest thou?
27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
28 And he said unto him, Thou hast answered right: this do, and thou shalt live.
What is it with folks here at BB? You are not arguing with me, you are arguing with Jesus!
You put in bold yourself, the word "IF." That designates a hypothetical; a conjecture. It is not unlike the statements given in 1Cor.13
1 Corinthians 13:1 Though I speak with the tongues of men and of angels, and have not charity, I am become
as sounding brass, or a tinkling cymbal.
2 And though I have
the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
3 And though I bestow all my goods to feed
the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing.
Here is what Paul DID NOT SAY:
1. He did not say he could speak with the tongues of men and of angels.
2. He did not say he could understand all mysteries.
3. He did not say that he had all faith, nor all knowledge.
4. He did not say that he could remove mountains.
5. He did not say that he was going to bestow all his good to feed the poor.
6. And he did not say he was going to give his body to be burned.
He never said any of those things.
They are subjunctive. They begin with "though," "if," "suppose." They are suppositions.
Suppose I do this; just suppose. If I do any of the above....it would be of no profit if it was not done with love. But he didn't do those things. He never claimed to.
The same grammatical structure is used in many of the examples you are using.
"If you will enter into life keep the commandments," or the converse--
"If you will keep my commandments you will enter into life."
The if is impossible and cannot be done. It is conditional to the promise being kept.
The law could not save anyone.
The Israelites were under the law. The Mosaic covenant was made at Mount Sinai. Who kept it? Not one of the Israelites were able to keep it, though it was a covenant, a promise. It was met with absolute failure. No one could keep the law. Thus Christ came to fulfill the law. He was the one that lived a perfect and sinless life that through him we might have eternal life, not through keeping the law.
Again and again, Jesus uses the example of the law to demonstrate the sinfulness of others.
