Now if you're saying that by "works", Paul is not including works of faith, then aren't you interpreting Paul to say that one must do "works of faith",
I don't use the term "works" of faith, because we are already in the process of rightly dividing the "works" of the law, from the "works" that James is describing.
James "works", is the work of obedience, or what the bible calls: the obedience of faith.
But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations
for the obedience of faith: Romans 16:26
The works that James is describing, establishes a principle of faith, that can not be disregarded if one desires to accomplish, what faith was meant to accomplish.
This principle holds true, whether it is faith for Salvation, or faith for building an Ark.
Faith comes by hearing God.
Faith comes from God.
Abraham's believing culminated,
in this act of obedience; in other words, Abraham's believing was proved to be genuine, or alive,
when tested.
Example: A Jewish man hears the Gospel, and believes, and rejoices with the joy of salvation, then later, he is persecuted by other Jews to turn back to the law and renounce Jesus or be stoned to death.
The man renounces Jesus, and turns back to practicing the law of Moses... and dies some years later, as a faithful follower of Judaism.
Did this man obey the Gospel command to repent; to turn to God. To change your mind about Who you serve?
If we understand that faith is the substance of things hoped for....and the evidence of things not seen, then it becomes quite clear what Peter means when he says these words... Though now you do not see Him, yet believing, you rejoice with joy inexpressible and full of glory,
receiving the end of your faith--
the salvation of your souls.1 Peter 1:8-9
The end of your faith, is the salvation of your soul.
So if we have faith in Jesus Christ for salvation,
we have the hope of salvation.
Jesus said it this way -
Those who
endure to the end will be saved.
Matthew 24:13
Paul says it like this -
And you, who once were alienated and enemies in your mind by wicked works,
yet now He has reconciled in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight--
if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Colossians 1:21-23
and again
12 Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God;
13 but exhort one another daily, while it is called "Today," lest any of you be hardened through the deceitfulness of sin.
14 For
we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end,
Hebrews 3:12-14
Paul describes this principle in more detail, but this should be enough to chew on for now.
