self-abasement

8. Resolved, to act, in all respects, both speaking and doing, as if nobody had been so vile as I, and as if I had committed the same sins, or had the same infirmities or failings as others; and that I will let the knowledge of their failings promote nothing but shame in myself, and prove only an occasion of my confessing my own sins and misery to God.
