So, without having to rely on someone else to answer for you, answer me this:
Was there a time when men were not under Law, then they were under the Law, then a time after that when they weren't?
God bless.
The Law(meaning the Law of Moses) was only given to ancient Israel, never to the Gentiles. The Law of Moses came to a halt when Christ said, "It is finished" and the curtain of the temple was torn in two - Matthew 27:51 And, behold, the veil of the temple was rent in twain from the top to the bottom. And then even ancient Israel itself as a nation was eliminated in 70 A.D.
The apostle Paul makes very clear in the book of the Romans that even though the Gentiles were not given the Law of Moses, that they still sinned even though they were not given the Law to keep, as we also see in Noah's day - Genesis 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
And Paul states it clearly in Romans 3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Thus, no man can be saved by law-keeping whether they have the Law or not, as all sinned in Adam. Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned
Romans 5:19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.
Salvation has always been and will always be by the sins of God's elect having been imputed to Christ and His payment of their sin debt on the cross. Christ lived on this earth and achieved a perfect righteousness which was imputed to the elect. The Holy Spirit regenerates them and gives them spiritual life, as God replaces their heart of stone with a heart of flesh, and He preserves them until their sojourn on this earth is completed.
“And when I passed by thee, and saw thee polluted in thine own blood, I said unto thee when thou wast in thy blood, Live; yea, I said unto thee when thou wast in thy blood, Live.” - Ezekiel 16:6 KJV
“A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.” - Ezekiel 36:26 KJV
“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.” - 2 Corinthians 5:21 KJV
“Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, saying, Blessed are they whose iniquities are forgiven, And whose sins are covered. Blessed is the man to whom the Lord will not impute sin.” - Romans 4:6-8 KJV
