"...he that professeth the gospel avows that the death of Christ doth crucify sin; that faith purifieth the heart; that the Holy Ghost quickens and enables the soul unto duty...These things are plainly, openly, frequently insisted on in the gospel. Hence the apostle presseth men unto obedience on the account of them; and, as it were, leaves them at liberty from it if they were not so, [Philippians 2:1-2]."
