Try reading Hebrews 11, and then tell me what you see.
I see nothing there which contradict the following words of the Lord Jesus spoken to the Jews who lived under the law that only "faith" was required for their salvation:
"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (Jn.6:47).
If it took more than faith for the Jews who lived under the law to be saved then why would the Lord Jesus tell them that His words are spirit and they are life?:
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life" (Jn.6:63).
I see nothing in Hebrews 11 which proves that it took more than His words to be saved. But according to your strange ideas the words of the Lord Jesus were not enough to bring life to those who believed because His words were insufficient by themselves to bring life to the Jews who lived under the law.
The Jews who lived under the law were born of God when they believed in the Lord Jesus:
"He came unto his own, and his own received him not. But as many as received him, to them gave he power to become the children of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God" (Jn.1:11-13).
If we are to believe your misguided ideas we must throw our reason to the wind and somehow trick our mind into believing that even though they were born of God they were not yet saved.
You may not like it, but the Jews knew exactly what was expected of them.
James 2:21-22 Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? 22 Seest thou how faith wrought with his works, and by works was faith made perfect?
You overlook what James wrote in the first chapter because he made it plain that faith is sufficient for salvation:
"Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures" (Jas.1:18).
Of course the Jews who lived under the law knew exactly what was expected of them in order to be saved because the Savior Himself told them the following:
"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (Jn.6:47).
You think that you know more about salvation that the Savior Himself knows!
