A.W. Pink: Arminianism and Dispensationalism deviate from the Reformed understanding of faith and justification

A.W. Pink highlights an important deviation within Arminian theology in grounding justification within faith itself, rather than the faith that believes unto Christ and His righteousness:

What is the relation of faith to justification? The Arminian answer to the question, refined somewhat by the Plymouth Brethren, is, that the act of believing is imputed to us for righteousness. One error leads to another. Mr. Darby denied that Gentiles were ever under the law, hence he denied also that Christ obeyed the law in His people’s stead, and therefore as Christ’s vicarious obedience is not reckoned to their account, he had to seek elsewhere for their righteousness. This he claimed to find in the Christian’s own faith, insisting that their act of believing is imputed to them "for righteousness." To give his theory respectability, he clothed it in the language of several expressions found in Romans 4, though he knew quite well that the Greek afforded no foundation whatever for that which he built upon it.

In Romans 4 we read "his faith is counted for righteousness" (v. 5), "faith was reckoned to Abraham for righteousness" (v. 9), "it was imputed to him for righteousness" (v. 22). Now in each of these verses the Greek preposition is "eis" which never means "in the stead of," but always signifies "towards, in order to, with a view to": it has the uniform force of "unto." Its exact meaning and force is unequivocally plain in Romans 10:10, "with the heart man believeth unto ["eis"] righteousness": that is, the believing heart reaches out toward and lays hold of Christ Himself. "This passage (Rom. 10:10) may help us to understand what justification by faith is, for it shows that righteousness there comes to us when we embrace God’s goodness offered to us in the Gospel. We are then, for this reason, made just: because we believe that God is propitious to us through Christ" (J. Calvin). (A.W. Pink, Justification, ch. 8)
