Faith untried may be true faith, but it is sure to be little faith. It is likely to remain stunted as long as it is without trials. Faith never prospers so well as when all things are against her. Tempests are her trainers, and lightnings are her illuminators. When calm reigns on the sea, spread the sails as you will, the ship will not move to it's harbor. But let the howling winds rush forth and rock the vessel until her deck is washed with waves and her mast sways under the pressure of the full and swelling sail. It is then that she makes headway toward her desired haven. No faith is so precious as that which lives and triumphs in adversity.
Faith increases in solidity, assurance, and intensity the more it is exercised with tribulation. Faith is precious and it's trial is precious too.
