"Christ calls men to carry a cross; we call them to have fun in His name. He calls them to forsake the world; we assure them that if they but accept Jesus the world is their oyster. He calls them to suffer; we call them to enjoy all the bourgeois comforts modern civilization affords. He calls them to self abnegation and death; we call them to spread themselves like green bay trees or perchance even to become stars in a pitiful fifth-rate religious zodiac. He calls them to holiness; we call them to a cheap and tawdry happiness that would have been rejected with scorn by the least of the Stoic philosophers."
(This comes from a little book called "Gems from Tozer", which is a compilation of excerpts from multiple sources.)
