I had terrible reflections upon my mind for many months, as I have already observed, on account of my wicked and hardened life past; and when I looked about me, and considered what particular providences had attended me since my coming into this place, and how God had dealt bountifully with me - had not only punished me less than my iniquity had deserved, but had so plentifully provided for me - this gave me great hopes that my repentance was accepted, and that God had yet mercy in store for me.
Under these reflections I continued very pensive and sad for near month, and did not go down to the Bath, having no inclination to be with the woman whom I was with before; lest, as I thought, she should prompt me to some wicked course of life again, as she had done; and besides, I was very loth she should know I was cast off as above.
I sent my gentleman a short letter, therefore, that I had obeyed his orders in all things but that of going back to the Bath, which I could not think of for many reasons; that however parting from him was a wound to me that I could never recover, yet that I was fully satisfied his reflections were just, and would be very far from desiring to obstruct his reformation or repentance.
