Reflecting on a period of time when John Newton found himself ‘easy prey’ to ‘the enemy’ regarding sin that he had supposed himself no longer capable, Newton writes (Works, Vol.1 p.58):
By the remembrance of this interval, the Lord has often instructed me since, what a poor creature I am in myself, incapable of standing a single hour without continual fresh supplies of strength and grace from the fountain head.
