According to the final paragraph, what effect does Equiano hope that his narrative will have on shaping the identity of early America?

From the text:

I have only therefore to request the reader's indulgence and conclude. I am far from the vanity of thinking there is any merit in this narrative: I hope censure will be suspended, when it is considered that it was written by one who was as unwilling as unable to adorn the plainness of truth by the colouring of imagination. My life and fortune have been extremely chequered, and my adventures various. Even those I have related are considerably abridged. If any incident in this little work should appear uninteresting and trifling to most readers, I can only say, as my excuse for mentioning it, that almost every event of my life made an impression on my mind and influenced my conduct. early accustomed myself to look for the hand of God in the minutest occurrence, and to learn from it a lesson of morality and religion; and in this light every circumstance I have related was to me of importance. After all, what makes any event important, unless by its observation we become better and wiser, and learn 'to do justly, to love mercy, and to walk humbly before God?' To those who are possessed of this spirit, there is scarcely any book or incident so trifling that does not afford some profit, while to others the experience of ages seems of no use; and even to pour out to them the treasures of wisdom is throwing the jewels of instruction away.
