All that is “necessary to salvation,” is contained in two virtues, “faith in Christ,” and “obedience to laws.” The latter of these, if it were perfect, were enough to us. But because we are all guilty of disobedience to God’s law, not only originally in Adam, but also actually by our own transgressions, there is required at our hands now, not only “obedience” for the rest of our time, but also a “remission of sins” for the time past; which remission is the reward of our faith in Christ. That nothing else is necessarily required to salvation, is manifest from this, that the kingdom of heaven is shut to none but to sinners; that is to say, to the disobedient, or transgressors of the law; nor to them, in case they repent, and believe all the articles of Christian faith necessary to salvation.
