Faith in ROMANS is the key to how someone becomes right with God. That is precisely what Paul was articulating in chapters 1-4. We are justified by faith alone, apart from works of the Law.
Faith in HEBREWS is what grants us endurance to stay right with God. We are not of those who shrink back, but of those who persevere [10.35-39] in "the assurance of things hoped for" [11.1].
Faith in JAMES is the conduit for good works in the Christian life. This is why faith without works is useless [Js 2.20]: because faith is descriptive of the life of a Christian and not just of the hoop one jumps through to become a Christian.

So, why is it so hard to see that these three do not contradict one another but are instead inextricably linked as a whole. Different situations call for preaching and teaching faith in different ways. But without this framework, legality, Antinomianism, and the faith healing prosperity gospel are "crouching at our door" [Gen 4.7]. Furthermore, none of this is ever divorced from the Holy Spirit graciously and sovereignly working in sinners "as He wills" [1 Cor 12.11, 18] to draw us, sustain us, empower us, and cause to serve the King for the kingdom.
