A practical atheist
A professed atheist—is a monster that we do not often meet with.
But the more absurd and astonishing phenomenon of a practical atheist; one who is orthodox in principle—but an infidel in practice—we find wherever we turn!
"Why do you call Me, 'Lord, Lord,' and do not do what I say?" Luke 6:46
"They claim to know God—but by their actions they deny Him. They are detestable, disobedient and unfit for doing anything good!" Titus 1:16
"Those who claim they belong to the Lord—must turn away from all wickedness." 2 Timothy 2:19
