Tenacity is more than endurance, it is endurance combined with the absolute certainty that what we are looking for is going to transpire. Tenacity is more than hanging on, which may be but the weakness of being too afraid to fall off. Tenacity is the supreme effort of a man refusing to believe that his hero is going to be conquered . . . If our hopes are being disappointed just now, it means that they are being purified . . . One of the greatest strains in life is the strain of waiting for God.
– Oswald Chambers –
