It is not enough to deliver from wrath, and to save from punishment; but in order to make a poor shiner happy, he must be qualified to enjoy. The circumcision of the heart, is the precious and blessed work of GOD the HOLY GHOST, who only can accomplish this. Hence the apostle tells us, that CHRIST is made of GOD to us, not only wisdom to enlighten, but righteousness to justify, sanctification to purify, and redemption to secure from every evil. 1 Corinthians 1:30.
