Adversity is the touchstone of character.

As some herbs need to be crushed to give forth their sweetest odour, so some natures need to be tried by suffering to evoke the excellence that is in them.

Hence trials often unmask virtues, and bring to light hidden graces.

Men apparently useless and purposeless, when placed in positions of difficulty and responsibility, have exhibited powers of character before unsuspected; and where we before saw only pliancy and self-indulgence, we now see strength, valour, and self-denial.
As there are no blessings which may not be perverted into evils, so there are no trials which may not be converted into blessings.

All depends on the manner in which we profit by them or otherwise.
