William Secker says - (Carnal Man vs. Christian Man)

"A carnal man may love his friends, but it is Christian man that loves his enemies."
The Nonsuch Professor p.58

But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.

Luke 6:35
