If the germ of the seed has to struggle to push its way up through the stones and hard sod, to fight its way up to sunlight and air, and then to wrestle with storm and tempest, with snow and frost, the fiber of its timber will be all the tougher and stronger.
There is good philosophy in the injunction to love our enemies, for they are often our best friends in disguise. They tell us the truth when friends flatter. Their biting sarcasm and scathing rebuke are mirrors which reveal us to ourselves. These unkind stings and thrusts are often spurs which urge us on to grander success and nobler endeavor. Friends cover our faults and rarely rebuke; enemies drag out to the light all our weaknesses without mercy. We dread these thrusts and exposures as we do the surgeon's knife, but are the better for them. They reach depths before untouched, and we are led to resolve to redeem ourselves from scorn and inferiority.
We are the victors of our opponents. They have developed in us the very power by which we overcome them. Without their opposition we could never have braced and anchored and fortified ourselves, as the oak is braced and anchored for its thousand battles with the tempests. Our trials, our sorrows, and our griefs develop us in a similar way.
The man who has triumphed over difficulties bears the signs of victory in his face. An air of triumph is seen in every movement.
John Calvin, who made a theology for the seventeenth and eighteenth centuries, was tortured with disease for many years, and so was Robert Hall. The great men who have lifted the world to a higher level were not developed in easy circumstances, but were rocked in the cradle of difficulties and pillowed on hardships.
"The gods look on no grander sight than an honest man struggling with adversity."
"Then I must learn to sing better," said Anaximander, when told that the very boys laughed at his singing.
Strong characters, like the palm-tree, seem to thrive best when most abused. Men who have stood up bravely under great misfortune for years are often unable to bear prosperity. Their good fortune takes the spring out of their energy, as the torrid zone enervates races accustomed to a vigorous climate. Some people never come to themselves until baffled, rebuffed, thwarted, defeated, crushed, in the opinion of those around them. Trials unlock their virtues; defeat is the threshold of their victory.
It is defeat that turns bone to flint; it is defeat that turns gristle to muscle; it is defeat that makes men invincible; it is defeat that has made those heroic natures that are now in the ascendency, and that has given the sweet law of liberty instead of the bitter law of oppression.
Difficulties call out great qualities, and make greatness possible. How many centuries of peace would have developed a Grant? Few knew Lincoln until the great weight of the war showed his character. A century of peace would never have produced a Bismarck. Perhaps Phillips and Garrison would never have been known to history had it not been for slavery.
