Context

“"Now I know that thou fearest God," i.e. "I have made thee know." Now He is speaking there of chaste fear, which is not apart from grace. Hence a man may know that he has grace. On the contrary, It is written (Eccles. 9:1) : "Man knoweth not whether he be worthy of love or hatred." Now sanctifying grace maketh a man worthy of God's love. Therefore no one can know whether he has sanctifying grace. I answer that, There are three ways of knowing a thing: first, by revelation, and thus anyone may know that he has grace, for God by a special privilege reveals this at times to some, in order that the joy of safety may begin in them even in this life, and that they may carry on toilsome works with greater trust and greater energy, and may bear the evils of this present life, as when it was said to Paul” source
