Or rather you are clueless about what he's talking about.
Did you read the quote? Probably not! Paul was talking about the Decalogue. Where is it written "Thou shall not covet" if not in the Decalogue? (Romans 7:7) Paul despised the Law, Hawkins. While Jesus taught to listen to "Moses" aka the Law, (Luke 16:29-31) Paul would teach the Jews to abandon the Jewish customs taught by Moses. (Acts 21:21)
God's plan, as He gradually reveals to humans, is to build an eternity we call Heaven for His creatures such as the angels and humans living with Him forever. However God hates something which we call sin.
Would you please provide us with the quote that God's plan is to build an eternity you call Heaven? What I have is that Adam & Eve were banished from the Garden of Eden to prevent them from eating of the tree of life and live forever. (Gen.3:22,23) It means that eternity is an attribute that belongs with God only and cannot be shared with man.
However under the influence of Satan, the first lineage of humans sinned when put in Eden (a place inside God's realm). Since then humans are driven out of God's realm, living in the current planet earth where Satan is literally said to be the god of this world. When humans are no longer inside God's realm, with Satan's influence being much stronger, no human can thus enter the final heaven by abiding the Law. This point is proven (by God) so it came the story of Noah. God's purpose for humans (to live the eternal Heaven) was defeated. Humans as a whole will fail the final judgment of God's Law. Thus the existence of earth serves no purpose but a pool of sins which God hates. It's thus time to destroy this pool of sins once and for all (by water).
You speak about Satan as a being and, there is no such a thing. Satan is only a concept to illustrated the evil inclination in man. On the other hand, Satan could not be literally the god of this world because God is of an absolute Oneness. There is no other god to share the universe with. (Isaiah 46:5)
Through the blood of Jesus Christ God can now grant a series of covenants as a mean of salvation to humans. A covenant simply says, "since you humans can't abide by God's Law in full, you only need to abide by a set-aside set of rules (such as Mosaic Law) to a said standard, such that you will be saved by God's Grace through Jesus Christ. Each and every covenant serves the main purpose of identifying and thus separating the righteous from the wicked. The righteous thus will be brought to Heaven legitimately under open witnessing (of angels and saints).
You have forgotten that Jesus was a loyal Jew who came to confirm the Law and the Prophets down to the letter. (Mat. 5:17-19) The Prophets of the Most High were inspired by God Himself to teach that no one can die for the sins of another. (Ezek. 18:3,20; Jeremiah 31:30) It means that salvation does not come through the blood of Jesus but through the obedience of God's Law. (Isaiah 1:18,19; Luke 16:29-31)
Satan (and his angels) on the other hand will stress his influence, humans will thus sin further to an extent that an older covenant may fail in identifying the righteous (the harvest). Then it is time for God to upgrade His covenant to a newer one by granting more Grace, such that His Elect (the righteous) will become savable.
It happens though, that the New Covenant upgraded by HaShem was established with the House of Israel and the House of Judah; no Gentiles included, unless they join God's Covenant with Israel according to Halacha aka Jewish law. (Isa. 56:1-8)
Romans 5:20-21 (NIV2011) 20 The law was brought in so that the trespass might increase. But where sin increased, grace increased all the more, 21 so that, just as sin reigned in death, so also grace might reign through righteousness to bring eternal life through Jesus Christ our Lord.
It had to be Paul because, the purpose of the Law has never been to increase trespasses but to increase Law observance so that people be saved from the troubles of life as a result of graves sins.
The New Covenant brought in directly by Jesus Himself became the final covenant because it has the maximum Grace granted. Under this covenant, our salvation is measured by our faith alone. Faith in Christ becomes the only rule (unlike Mosaic Law) applied for us to be saved. You believe with Faith in a correct fashion then you will be saved (brought to the final Heaven) legitimately and openly.
Jesus brought no new covenant. The opposite is rather true that he taught us all to listen to "Moses" aka the Law according to the Covenant given to Israel in the Mount Sinai. (Luke 16:29-31; Mat. 5:17-19)
Whether one can fulfill what a covenant said will be judged by Jesus Christ Himself, because all the Grace is granted under His name. His blood gives Him the right to grant the Grace to anyone He wishes though He will judge fairly and He will judge what is deep inside your heart. The angels and saints will also be the witnesses to see if you have fulfilled the covenant. As for the New Covenant, Jesus will judge if your faith qualifies you to enter the final Heaven.
Sorry to rain on your parade but Jesus has been dead for 2000 years and, the dead can judge nothing if you read Ecclesiastes 9:5,6.
If you are considered (by Jesus Christ) to fail the covenant, then you will be judged by the Law which will sentence you to death (the second death) with whatever consequences it brings.
"The second death!" What on earth are you talking about! For a second death to exist, one must return from the first one and,according to the gospel of Jesus which was the Tanach, once dead, no one will ever return from Sheol aka the grave if you read II Samuel 12:23; Isaiah 26:14; Job 7:9; Psalms 49:12,20; etc.
