It is the Christian claim that it is impossible to keep the law.
The Mr. Batman argument wold go as follows,
The “Mr. Batman” argument is a way of stating that once you break the law, you are guilty of death and therefore you need the “blood of Jesus” to heal you or to save you from this punishment.
A simple reading of the text shows this is an incorrect opinion. Pasages such as Exodus 16 show that even when a particular law or commandment was broken, it did not represent a breech of covenant;
27 And it came to pass, that there went out some of the people on the seventh day to gather, and they found none.
28 And the Lord said unto Moses, “How long will you refuse to keep my commandments and my laws?
29 As the Lord has given you the sabbath, he will give you on the sixth day the bread of two days: Therefore abide every man in his place, let no man go out of his place on the seventh day.”
30 So the people rested on the seventh day.Exodus 16:27-30
Another famous example would be when King David was forgiven by the Lord (by Nathan).
The question then becomes whether or not this is just a case study or if in addition to this there is an actual law given in the Torah. In fact, there is;
6 “Speak to the people of Israel, When a man or woman commits any of the sins that people commit by breaking faith with the Lord, and that person realizes his guilt,
7 he shall confess his sin that he has committed. […]
Frankly speaking, it is in fact a law itself to confess your sins;
7 […] And he shall make full restitution for his wrong, adding a fifth to it and giving it to him to whom he did the wrong.
8 But if the man has no next of kin to whom restitution may be made for the wrong, the restitution for wrong shall go to the Lord for the priest, in addition to the ram of atonement with which atonement is made for him.
9 And every contribution, all the holy donations of the people of Israel, which they bring to the priest, shall be his.
10 Each one shall keep his holy donations: whatever anyone gives to the priest shall be his.” Numbers 5:6-10
and further, there are means of restitution given by the torah – in this case a punishment (such as a fine) which fits the nature of the transgression.
Even in a case where the people of Israel commit a major breech of the covenant, God has already pre-ordained that he will never abandon his covenant with them:
44 And yet for all that, when they are in the land of their enemies, I will not cast them away, neither will I abhor them, to destroy them utterly, and to break my covenant with them: for I am the Lord their God.
45 But I will for their sake remember the covenant of their ancestors, whom I brought forth out of the land of Egypt in the sight of the heathen, that I might be their God: I am the Lord.Leviticus 26:44-45
One may note that even within this passage is the idea that one may turn from his sins, from the covenant which he had broken, and return to the lord;
40 If they shall confess their iniquity, and the iniquity of their fathers, with their trespass which they trespassed against me, and that also they have walked contrary unto me;
41 And that I also have walked contrary unto them, and have brought them into the land of their enemies; if then their uncircumcised hearts be humbled, and they then accept of the punishment of their iniquity:
42 Then will I remember my covenant with Jacob, and also my covenant with Isaac, and also my covenant with Abraham will I remember; and I will remember the land. Leviticus 26:40-42
We may also bring many other passages such as the entirety of Ezekiel 18; relevant quote,
21 “But if a wicked person turns away from all his sins that he has committed and keeps all my statutes and does what is just and right, he shall surely live; he shall not die. 22 None of the transgressions that he has committed shall be remembered against him; for the righteousness that he has done he shall live. 23 Have I any pleasure in the death of the wicked, declares the Lord God, and not rather that he should turn from his way and live? Ezekiel 18:21-23
Even though we know God will not do this (see Lev. 26, etc.) Christians will still make this claim from time to time. This is in fact a misreading of Jeremiah. See: “Did God divorce the jews?” for a full exposition, but in short, Jeremiah 3:8 shows that even if we say that God divorced Israel (which he did not; see Jeremiah 3:12-13 next), this refers to the idolatrous nation of Northern Israel and not Judah, which is clear from the passage. So even if this happened, there is still the problem of righteous Judah – or at the very least a righteous remnant (see after).
The point here is in fact that directly after this God says that if Israel returned to him he would forgive them (Jeremiah 3:12-13). Jeremiah 3:14-18 continues to include Jerusalem. Therefore no rational person would believe that God had “divorced” or in any way abrogated the covenant he made with Israel. This message is in fact repeated again in Jeremiah 3:19-22, if reading it once wasn't enough!
There is a concept called the righteous remnant which all Christians agree with as even Paul acknowledges their existence. Ultimately if the above is not proof enough (then one would wonder what proper proof would be, if not the very word of God) then one may point out the existance of the righteous remnant.
The righteous remnant is in fact the mighty and outstretched hand of the Lord which is protecting and preserving the Jewish people according to his covenant with them. Please see Righteous Remnant for more information.
It is the Christian position that you do not need to keep the law because it was fulfilled in Christ. There are many ways of explaining this and many scriptures such as saying written on your heart, etc.
What does Paul say about this?
It should be clear from the writings of Paul that his explicit permission is that the law is no longer meant to be kept because the Christians are now under a new covenant by whichever mechanism and purpose they are.
Our only question is whether or not this is scriptural.
It is the position of the word of God that the Law can only be kept by doing it. We will examine two classes of verse here; one, the statement that the law must be done (performed; by works) (A) and two, that this kind of observance will never change in the future (B).
These are verses which discuss that the covenant must be kept by doing it with works (performing an act of volition).
These are verses which discuss that the mode of observation will not change in the future.
11 from the time that I appointed judges over my people Israel. And I will give you rest from all your enemies. Moreover, the Lord declares to you that the Lord will make you a house. 12 When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come from your body, and I will establish his kingdom. 13 He shall build a house for my name, and I will establish the throne of his kingdom forever. 14 I will be to him a father, and he shall be to me a son. When he commits iniquity, I will discipline him with the rod of men, with the stripes of the sons of men, 15 but my steadfast love will not depart from him, as I took it from Saul, whom I put away from before you. 16 And your house and your kingdom shall be made sure forever before me. Your throne shall be established forever.’” 2 Samuel 7:11-16 (ESV)
