Here's some word vomit for you:
There comes a point when the problem with praying is not that at the outset it is a struggle to begin, to focus, to have a certain mindset; but that once you finally receive the gift of His presence, you can't seem to want to STOP. When the truest pleasure comes from spending time alone with Him and everything else seems bland and mediocre in comparison, God has become more your crutch than ever.
There have been moments when I struggle to find some kind of motivation to even rouse myself from praying to eat or do what are normally enjoyable activities. Perhaps at this point, other people are confused or think you must be depressed (which may be the case at some times). But I find that in those moments God has shown me the greatest joy of eternity. "Amen" is your least favorite word. Bent knees and folded hands are hardly the beginning of it.
It's even ironic--we often come to God hoping He will fill up the discontentment of our earthly lives. Instead, when we find Him we only realize that the peace that comes in knowing Him only makes the earthly discontentment all the greater.
