The most inhuman people in the world

(The following remark is by an infidel)

"Christians, if they are not the most inhuman people
in the world, cannot believe what they profess--that men
without repentance and faith must perish eternally--or they
would be more earnest in endeavoring to save them. If I
believed what they profess to believe--I would scarcely
cease day or night to warn others of the wrath to come."
