one of the most memorized and beloved bible passages is the 23rd psalm and it talks about rest...
1-3 God, my shepherd! I don't need a thing.
You have bedded me down in lush meadows,you find me quiet pools to drink from.
True to your word,
you let me catch my breath
and send me in the right direction.
being tired, rundown, overwhelmed by life and problems or challenges basically creates a spiritual mononucleosis, we're exhausted and ineffective and can barely put one foot in front of the other...yes, God uses our weakness? but He wants us to be strong through Him, the only way we can do that is to be refreshed BY Him, we need rest...yes, it's wonderful if that rest can be literal and if He allows physical and emotional as well as spiritual renewal... but i truly believe that God shows us the most amazing times of rest, regrouping and re-energizing in order for us to enter the "real world" with a heart for Him..."True to your word, you let me catch my breath and send me in the right direction"...doesn't get much better than that:)
