The only way I get through stuff like this is because I am passionate about the end result. I have found that I can sustain that type of effort for about six days before I have to do something else.
But that is part of this assignment of serving our Lord is it not? Not everything we do is exciting. Some of it perhaps most of it is just discipline. Doing what needs to be done whether we feel like it or not.
Perhaps that is really the height of worship.
