We must loathe lukewarm people. This message is found throughout scripture. Those who are violent are better off, even if initially they do evil. We cannot expect anything from souls who are slumbering; from those who do good – or think they do good – by abstaining from evil. A heart that is on fire, even if it bewilders us at times, is equipped to serve. God freely chooses his saints from among the great sinners, but never from among those who are lukewarm – from those who do not risk anything.
