Your version of the bible has changed the little words "Faith of Jesus, to read "faith in Jesus" which makes it man's faith instead of Jesus's faith.

The Greek seems ambiguous regarding if it is "in" or "of" in my lay opinion, but assuming the KJV is correct,
then Paul still seems to be saying that no one will be justified by (in bold)
Galatians 2
15We who are Jews by birth and not Gentile “sinners”
16know that a man is not justified by
works of the law,
but by faith in Jesus Christ. So we, too, have believed in Christ Jesus, that we may be justified
by faith in Christ and not by
works of the law, because by
works of the law no one will be justified.
Which these are not, for example
Luke 10
8If you enter a town and they welcome you,
eat whatever is set before you.
Matthew 5
38You have heard that it was said, ‘Eye for eye and tooth for tooth.’ 39But I tell you not to resist an evil person. If someone slaps you on your right cheek, turn to him the other also;
Galatians 5
2Take notice: I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all.
John 8
4and said, “Teacher, this woman was caught in the act of adultery.
5In the Law Moses commanded us to stone such a woman. So what do You say?”
6They said this to test Him, in order to have a basis for accusing Him. But Jesus bent down and began to write on the ground with His finger.
7When they continued to question Him, He straightened up and said to them, “Let him who is without sin among you be the first to cast a stone at her.”
8And again He bent down and wrote on the ground.
9When they heard this,
b they began to go away one by one, beginning with the older ones, until only Jesus was left, with the woman standing there.
10Then Jesus straightened up
c and asked her, “Woman, where are your accusers?
d Has no one condemned you?”
11“No one, Lord,” she answered.
“Then neither do I condemn you,” Jesus declared. “Now go and sin no more.”
