Feast of Nicholas, Bishop of Myra, c.326 He that is alive may know that he was born, though he know neither the place where nor the time when he was so; and so may he that is spiritually alive, and hath ground of evidence that he is so, that he was born again, though he know neither when, nor where, nor how. And this case is usual in persons of quiet natural tempers, who have had the advantage of education under means of light and grace. God ofttimes, in such persons, begins and carries on the work of his grace insensibly, so that they come to good growth and maturity before they know that they are alive.
