(21) But now the righteousness of God apart from the law has been revealed, being witnessed to by the Law and the Prophets,

(24) Being justified freely by his grace, through the redemption that is in Christ Jesus,
(25) Whom God hath proposed to be a propitiation, through faith in his blood, to the shewing of his justice, for the remission of former sins,
(26) Through the forbearance of God, for the shewing of his justice in this time: that he himself may be just and the justifier of him who is of the faith of Jesus Christ

The Faith of Jesus, at first glance, is Judaism (Matthew 5:17-18) as it would imply for any believer and the religion that the person practices. For example, the faith of the Pope is Catholicism because Catholicism is a branch of Christianity.
However, the 'Faith of Jesus, Faith of Christ, or Faith of Jesus Christ' does not imply Judaism because Jesus was born Jew and, as such, no Jew would have any conflict with Jesus within Judaism. To wit, Jesus even advocates that nothing in Moses and the Prophets may be changed and that it is easier for heavens and earth to disappear than for any loosening or abolition of anything in Moses (Matthew 5:17-18, Luke 16:17).
Thus, we must understand that the 'faith of Jesus' which was being talked about is not the obvious but a totally new dimension in Judaism that got those who were not baptized very riled up. Keep also in mind that the new dimension (Gospel) revived or brought up by Jesus was to be preached and taught in Jerusalem first and that it is not going to be a different Gospel when it has out of Zion to the Gentiles.
Paul, before his compulsory conversion, exemplified the attitude of the rulers and of other zealots against those who hold to the new 'faith of Jesus' (Acts 24:24-25). It is kind of mental torture to the Jews for Paul to tell them that 'man is not justified by the works of the Law but by the 'faith of Jesus Christ' (Galatians 2:16). They could not grasp the declaration of Jesus that He came to fulfill the Law, which cancelled the rites in the Temple and their sabbaths in the Law.
Understand tha the unbaptized Jews were not in the wrong if you know about the immutability of the law of Moses as even Jesus reasserts it. Yet, again, they did not get baptized so that they could see the Messiah whom even the Samaritan woman saw and to whom Jesus opened to without parables to tell her that He is indeed the Messiah. Jesus withheld the confession of being the Messiah from the Jews (Matthew 16:20) and the Messiah is even born YHWH God (Luke 2:11). Their heart could not be opened for understand the voice of their own Messiah YHWH (Luke 2:11). Jesus brought about a fulfillment not a change. More than that, He is the Author of the Law.
Deuteronomy 5:32 ASV
(32) Ye shall observe to do therefore as Jehovah your God hath commanded you: ye shall not turn aside to the right hand or to the left.
Deuteronomy 12:32 ASV
(32) What thing soever I command you, that shall ye observe to do: thou shalt not add thereto, nor diminish from it.
Morally, the Disciples were made to understand the clue of the Gentiles receiving the Holy Spirit, even though they were uncircumcised. We know that Peter was taught also that a new age had come to Judaism concerning the forbiddance of mingling with the Gentiles.
The new age (Gospel) in Judaism was the 'faith of Jesus' which is repentance and remission of sins to all, Jews and the world, in His name with Moses and the Prophets still as the behavioral foundation of the Faith because He died for us (ransomed us) and was risen defeating death and, thereby, reconciled the world through Him with God the Father whom we and Judaism did not know existed until Jesus made Him known (John 17:25, Romans 3:21-31).
Obsoleteness of the 'works (tasks, services inside the Temple) of the law' not obsoleteness of the law (Romans 7:7)
The works: no more killings of the Lamb, of the goats, no more day of atonement (Romans 3:25), et cetera, because Jesus (God) died and taught us (John 6:45, Isaiah 54:13) how to pray to God the Father to ask for the forgiveness of our sins in His name. Jerusalem was not going to be around to keep on performing 'the works of the law'.
Christian or Messianic Judaism (not Christianity though) of justification by faith or belief of Jesus
Paul teaches that 'we have believed in Jesus Christ, that we might be justified by the faith of Christ' (Galatians 2:16) and the services, the tasks, the acts, the works, at the Temple for atonement. (When you read faith understand 'belief, trust'). Jesus said it all in John 3:16 that God the Father gave Him as a ransom for us so that if we believe in Him (which is the 'Faith or belief of Jesus') we will regain our immortality. Believing in Jesus entails living life believing that He is YHWH God (Luke 2:11, Romans 10:0-11) while practicing His commandments (Exodus 20:10; Deuteronomy 5:10; John 14:15, 21; Romans 7), and loving one another (John 13:34) without the fulfilled works of the law.
Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. Galatians 2:16 KJV
Justification by faith is the same phrase as 'justified by faith of Christ' which simply means that all men now just have to believe that the killings of animals for atonement are no longer necessary with the advent of Jesus because those rites were to make understand what the body of Jesus was to suffer for the redemption of men and because Jesus has always had the power to forgive our sins (Luke 5:24) without the blood of the animals. The Jews were to grapple with the 'faith of Christ or justification by faith' roadblock to their salvation while the world who was to receive the Gospel of repentance and remission of sins by Jesus does not have to overcome the 'faith of Jesus or justification by faith' because the culture of the rites at the Temple was not part of their upbringing. The Jews first, then the world, are to accept the new means of justification.
From that understanding vantage point of 'faith (belief) of Jesus or justification by faith', it does not amount to much when someone says that we just need to have faith in Jesus and, by that, implying that nothing else is required to be saved. Faith of Jesus or justification by faith just teaches 'no more killings of animals for atonement of sins' (Romans 3). Faith of Jesus or justification by faith now implies the confession of our sins to God the Father in the name of Jesus.
Faith of Jesus or justification by faith does not teach that we no longer have to keep the seventh day sabbath to be saved because we only need faith. Jesus NEVER implies that (Matthew 5:17-18, Luke 16:17), James teaches that the keeping of all the other portion of the law is necessary (James 2:10), and Paul stresses that point of keeping the law very clearly (romans 7). Otherwise, Paul says, we have no way of knowing what sin is and what to obey to be saved.
Paradoxically, there is a kind of 'works' which are required in order to validate 'faith (belief) of Jesus or justification by faith' (James 2:14-26).
Therefore, if you claim that you are saved because you believe in Jesus or you have faith in Jesus or you have faith of Jesus or you have a personal relationship with Jesus but you also reject anything in the Law (Matthew 5:17-18, Luke 16:17, James 2:10), 'ye therefore do greatly err' (Mark 12:27).
The 'faith (belief) of Jesus or justification by faith' does not absolve any man from the responsibilities of the Law of Moses and the Prophets. Again, it just means no more atonement from the blood of animals.
James 2:24 ASV
(24) Ye see that by works a man is justified, and not only by faith.
James 2:24 ABP
(24) See therefore that by works [is justified a man], and not by belief only!
James 2:24 EMTV
(24) You see then that a man is justified by works, and not by faith only.
Another paradox of faith (belief) and works: 'by grace you are saved through faith, not of works'. Complying with all the law of Moses and the Prophets cannot save us. Grace catalyzes faith and works into salvation.
Ephesians 2:8-11 EMTV
(8) For by grace you are saved through faith, and that not of yourselves; it is the gift of God,
(9) not of works, lest anyone should boast.
(10) For we are His handiwork, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Acts 22:7-8 ASV
(7) And I fell unto the ground, and heard a voice saying unto me, Saul, Saul, why persecutest thou me?
(8) And I answered, Who art thou, Lord? And he said unto me, I am Jesus of Nazareth, whom thou persecutest.
Matthew 16:18 ASV
(18) And I also say unto thee, that thou art Peter, and upon this rock I will build my church; and the gates of Hades shall not prevail against it.
1 Corinthians 15:9 ASV
(9) For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.
Galatians 1:13 ASV
(13) For ye have heard of my manner of life in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and made havoc of it:
