Excerpts from Impressions, by Martin Wells Knapp, 2

CHAPTER I
IMPRESSIONS -- THEIR ORIGIN

An impression is defined as "an influence on purposes, feelings or actions."

While we are free to choose the right or wrong, yet we are continually acted upon by influences which impress in different ways. Some of them come silently as the sunshine; others come like the lightning's stroke or thunder's peal; others like gentle zephyrs, and some like the devastating tornado. Every impression has a source. Back of all operating second causes there is with each impression a designing mind which is the source of it. God is the author of all good impressions, Satan of all that are evil.

Hence all impressions are naturally divided into two Classes:
1. Those from our Father, which we will call "Impressions from above." These, if followed ripen into convictions.
2. Those from the devil, which we will call "Impressions from below."
