Pastor Andrew Fuller (1754-1815) warns his own daughter Mary that she is not aware of just how evil a sinner she is

To Mary Fuller

Are you convinced of your having done deeds worthy of death, eternal death?

The skull of Adam at the foot of the Cross: detail from a Crucifixion by Fra Angelico, 1435

And is it so, my dear Mary, that your desire is to the Lord and to the remembrance of his name?  Are you convinced of your having done deeds worthy of death, eternal death; and that all your hope and help is in the Lord Jesus Christ?  Is he precious to your soul ? And are you willing to give up all your sins, and to be his servant for ever ? If so, I know of nothing that ought to hinder your being baptized in his name. To see you thus put on the Lord Jesus Christ, will afford the greatest pleasure to us, though it may be a pleasure mixed with trembling. You are, at present, my dear, but little acquainted with the snares and temptations of the world, with the fickleness and sinfulness of your own heart, and with the difficulty, on these accounts, of persevering in the good ways of the Lord; preserving a conscience void of offence towards God and towards man: but, if God has begun the good work in you, it will be carried on. There is strength to be had from above; and we are encouraged to ask it of him.
