In our natural state we are totally depraved. No inclination to holiness exists in the carnal heart; and no holy act can be performed, or service to God rendered, until the heart is changed. This change, it is the office of the Holy Spirit to effect. Pardon, justification, and adoption, are changes in a man’s condition; but if no other change were wrought, the man would remain a slave to sin, and unfit for the service and enjoyment of God. Grace, therefore, does not stop with a mere change of condition, but it effects also that change in the character, without which the individual could not participate in the holy enjoyments of heaven, or be fitted for the society of the blessed.
