Our whole life is beset with temptations. Satan watches all opportunities to break our peace, to wound our consciences, to lessen our comforts, to impair our graces, to slur our evidences, and to damp our assurances. Oh! What need then have we to be always upon our watch-tower, lest we be surprised by this subtle serpent.  Watchfulness includes a waking, a rousing up of the soul. It is a continual, careful observing of our hearts and ways, in all the turnings of our lives, that we still keep close to God and his Word. [PRASD]
