Love is kindled in a flame, and ardency is its life. Flame is the air which true Christian experience breathes. It feeds on fire; it can withstand anything rather than a feeble flame; but when the surrounding atmosphere is frigid or lukewarm, it dies, chilled and starved to its vitals. True prayer must be aflame.
Doctors put drugs of which they know little into bodies of which they know less for diseases of which they know nothing at all.
