A Discourse of the Cleansing Virtue of Christ's Blood

The Blood of Christ has a virtue to cleanse. It does not actually cleanse all, but only those that believe. Nor does it cleanse them from new sins, but upon renewed acts of faith. There is a sufficiency in it to cleanse all, and there is an efficacy in it to cleanse those that have recourse to it. As when we say a medicine purges such a humour, we understand it of the virtue and quality of the medicine, not that it purges unless it be taken in, or otherwise applied to the distempered person.
