Vigilance guides and protects believers like a lamp or beacon in darkness.
Vigilance is the safety-lamp of life. What the lighthouse is to the vessel in the murky night, nearing the rock and treacherous banks; what the torch is to the traveller who has been enveloped in thick mists; what the lantern is to the miner who creeps from gallery to gallery along the low corridors which penetrate the bowels of the earth wherein the fire-damp hangs round about this way; what the genial blaze on the cottage hearth is to the shepherd as he comes from afar over the morass or moor; what the branch of the green tree was to Columbus as it floated past his vessel's side, the sure and blessed harbinger of a not distant land, —such is vigilance to man's life.
