They grumbled in their tents
and did not obey the LORD.
(Psalm 106:25)

Centuries later..... this is me.  I may not be in a tent, but otherwise it's the same scenario.  Grumble and disobey.  Even I get tired of listening to myself grumble.  I can't imagine the Lord listening to me (plus billions of others) without wanting to remind me (in a not-so-gentle way) of all of my blessings, all of which were given to me by God, Himself.
