The first object, therefore, for which it is appointed by the Lord, is to be a sign and evidence of our purification, or (better to explain my meaning) it is a kind of sealed instrument by which he assures us that all our sins are so deleted, covered, and effaced, that they will never come into his sight, never be mentioned, never imputed. For it is his will that all who have believed, be baptised for the remission of sins.
