A quote from William Gurnall:
Nothing should have a more powerful effect upon a saint's spirit than to consider his blissful estate in heaven as being the reward of all his conflicts here on earth. This sword should cut the very sinews of temptation and behead those lusts which defy whole troops of other arguments. How can sin co-exist with the hope of such glory? It is when the thoughts of heaven are long out of the Christian's sight, and he forgets his hope of that glorious place, that he begins to set up some idol as Israel set up the calf and worshiped it in the absence of Moses. Only let heaven come into view, and the Christian's heart will be well warmed with thoughts of it. You may as soon persuade a king to throw down his royal diadem and wallow in the mud with his robes on, as convince a saint to sin when his heart is filled with the expectation of heaven's glory.~William Gurnall (The Christian In Complete Armor Volume One, Chapter 4, Part 2)
