B. B. Warfield (Works, 7:130):

Sin and Christ; ill desert and no condemnation; we are sinners and saints all at once! That is the paradox of evangelicalism. The Antinomian and the Perfectionist would abolish the paradox—the one drowning the saint in the sinner, the other concealing the sinner in the saint. We must…out of evangelical consciousness, ever see both members of the paradox clearly and see them whole.
