This means that if pastoring involves, you know, pastoring, then it matters little how vociferously some may say "there are no guarantees in life." There is one on which nearly any pastor can count: spiritual fatigue will happen. There will be moments or perhaps months where Jesus seems conspicuously absent, and no amount of Footprints in the Sand reviewing will convince us otherwise.
