"Spiritual gifts are for the confirmation of the gospel and the spiritual edification of the church. But gifts do not bring salvation and can be given to those who know nothing of grace in their hearts. So it is incumbent on all who have received spiritual gifts not to look to them as evidences of being truly regenerated, but to spiritual graces. Some have been deceived into thinking they have grace when they only have gifts. So the presence of spiritual gifts can mislead us into thinking that all is well when great apostasy is taking place.
Gifts, without grace, have no influence on the soul and they work only at special times and on special occasions. But grace affects the whole person at all times and in all duties. Grace works holy obedience in the soul. Gifts do not. Gifts are not, and can never be, the measure of our growth in grace..." —John Owen (1616-1683)
