Yes. Of course we can't say what and how God might have revealed of his Son if he had decreed something different. But neglecting that unascertainable hypothetical, Romans 9 is fairly clear that both reprobation and election serve to display some aspect of the truth about God. We beheld the glory as of the only-begotten of the Father, full of grace and truth, because the Son of God was manifested to destroy the works of the devil, if I may conflate John with 1 John.
