Justification Other Than by Faith?

And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. – Gal 3:8

Is there a justification before the LORD grounded in light received? If Jobal, a man on the other side of the world, has received any measure of spiritual light, is this general revelation a ground of justification? Jobal, a non-believer in Jesus Christ, is certainly one of the heathen mentioned above yet some would have a doctrine promoted that God will justify a man based on what measure of light he has received rather than an explicit faith. Some will state that Jobal is justified by the work of Christ on the cross without an explicit faith in the person of that work. However, the scriptures seem to state something quite different.

 Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; -  Ro 3:24-25

Here we find the work of the cross, the shed blood of Jesus Christ, made efficacious by faith in that particular work. It was not the work or atonement alone that saves. Faith is also required. Our Calvinist fellows are often found to equate the atonement with salvation itself using that distinction to oppose unlimited atonement. The passage from Romans not only sets that error aside but it also goes to the heart of the inclusivist error that some of us have been engaged in recently. There is no propitiation lacking faith and therefore it is not the work of Calvary that saves. The work of Christ is a provision made effective only through faith and in that it is not appropriate for the inclusivist to state that this atonement satisfies the requirement for justification. This is clearly applicable to the heathen as well as the Hebrew as noted in Gal 3:8. Was Rahab of Jericho saved by general revelation or did she find redemption through faith? The scriptures tell us she found her refuge by faith.

 By faith the harlot Rahab perished not with them that believed not, when she had received the spies with peace. - Heb 11:31

Why is it that the inclusivist relies on philosophy and emotional appeals yet cannot present a scriptural argument supporting a general revelation salvation? If a scriptural case cannot be made, why argue against the scriptural case that can easily be presented?
