Where does the justification for The New Testament doers of the law in Romans 2:13 originate from?

Obviously we cannot follow anything involving the temple since it has been knocked down.

Galatians 3:10 For all who rely on the works of the law are under a curse, as it is written: “Cursed is everyone who does not continue to do everything written in the Book of the Law.”

You either follow ALL of the law, or you are a lawbreaker.

Romans 2:11-15
11 For there is no respect of persons with God. 12 For whosoever have sinned without the law, shall perish without the law; and whosoever have sinned in the law, shall be judged by the law. 13 For not the hearers of the law are just before God, but the doers of the law shall be justified. 14 For when the Gentiles, who have not the law, do by nature those things that are of the law; these having not the law are a law to themselves: 15 Who shew the work of the law written in their hearts, their conscience bearing witness to them, and their thoughts between themselves accusing, or also defending one another,

Ezekiel 36:27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them

Actually the Gentiles did have some specific Laws to abide by. Acts 15:
19 Wherefore I judge that we trouble not them that from among the Gentiles are turning to God,

20 but that we write to them to abstain from the pollutions of idols, and from sexual lewdness, and from what is strangled, and from blood.

This even exists today.

The Bible says it is not hard to follow the Law. I believe when we listen to the Holy Spirit it will be even easier.

How's that working out for you regarding finding a priest to inspect your sacrificial lamb at the Temple in Jerusalem?

impossible ... the law has been scrapped for the church.

Where does it say that? We are not saved by faith but saved people do good works. The law does not save us but it does show us when we are breaking the law.

Romans 2:13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.

the ability to attain to these is by grace received. to try to attain to them by obeying commands actually magnifies the sin and makes it likely we will fall.

Have done with the law and walk in the Spirit.

We are in the NEW covenant, the old covenant is finished.

The New Covenant is God putting his Holy Spirit inside of us to follow his law. This is a Covenant written into our hearts instead of on stone or paper.

Jeremiah 31:31-34 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.

You forgot to highlight the most important part: "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..."

What you're saying is that only the place where the covenant is written is changed. No. Its very essence is different.

"they shall all know me"

This is understood as knowing the Lord intimately: His very being and nature. Previously he wrote "although I was an husband unto them". So this "knowing" is not knowledge, it is about being one flesh with God. How is this possible? Because His nature is put into all who are in Christ. Together the saints actually BECOME the body of Christ: His flesh and His bones. When you are in the Son and the Son is in you, you need no man to teach you about your Father. Why? Because the nature of the son IS the nature of the father. This is true in the natural as well as the spiritual.

God said eating swine is an abomination. Did he change his mind?

You mean like this:

The next day at about the sixth hour, as the men were approaching the city on their journey, Peter went up on the roof to pray. He became hungry and wanted something to eat, but while the meal was being prepared, he fell into a trance.

He saw heaven open and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals and reptiles of the earth, as well as birds of the air. Then a voice said to him: “Get up, Peter, kill and eat!”

“No, Lord!” Peter answered. “I have never eaten anything impure or unclean.”

The voice spoke to him a second time: “Do not call anything impure that God has made clean.”

This happened three times, and all at once the sheet was taken back up into heaven.

Doesn't specifically mention swine but it does mention things that were impure or unclean under the law.

Now, God made them clean.

God didn't change His mind. Jesus fulfilled the law. God was showing Peter that that the law no longer governed his life.

And how did God get the word out to Peter? Not through a written scripture or another stone carving... God spoke to Peter's spirit. Spirit to spirit was made possible by Christ's indwelling Spirit in Peter.

Mark 7:19
ESVsince it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.)

NIVFor it doesn't go into their heart but into their stomach, and then out of the body.' (In saying this, Jesus declared all foods clean.)

NASBbecause it does not go into his heart, but into his stomach, and is eliminated?' ( Thereby He declared all foods clean.)

CSBFor it doesn't go into his heart but into the stomach and is eliminated" (thus he declared all foods clean ).

NLTFood doesn’t go into your heart, but only passes through the stomach and then goes into the sewer.' (By saying this, he declared that every kind of food is acceptable in God’s eyes.)

Although unclean food was used as an example for Peter the context of the whole vision was about God making the gentiles clean.

If you read Isaiah you will see that before the end times judgement that God still views swine as an abomination.

Isaiah 66:16 For by fire and by his sword will the LORD plead with all flesh: and the slain of the LORD shall be many. 17 They that sanctify themselves, and purify themselves in the gardens behind one tree in the midst, eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith the LORD.
