Seeking Heaven through righteousness is not seeking righteousness, but something else;--it is not loving goodness for goodness' sake, but for its rewards.
Heaven never defaults. The wicked are sure of their wages, sooner or later.
The brightest crowns that are worn in heaven have been tried, and smelted, and polished and glorified through the furnaces of tribulation.
We may learn by practice such things upon earth as shall be of use to us in heaven. Piety, unostentatious piety, is never out of place.
There have been men who could play delightful music on one string of the violin, but there never was a man who could produce the harmonies of heaven in his soul by a one-stringed virtue.
Many a man who might walk over burning ploughshares into heaven stumbles from the path because there is gravel in his shoes.
