Charles Finney
Finney wrote how God gave him mighty infillings of the Holy Spirit “that went through me, as it seemed, body and soul. I immediately found myself endued with such power from on high that a few words dropped here and there to individuals were the means of their immediate conversion. My words seemed to fasten like barbed arrows in the souls of men. They cut like a sword. They broke the heart like a hammer.
Multitudes can attest to this...Sometimes I would find myself in a great measure empty of this power. I would go and visit, and find that I made no saving impression. I would exhort and pray with the same results. I would then set apart a day for private fasting and prayer...after humbling myself and crying out for help, the power would return upon me with all its freshness. This has been the experience of my life.”
