Danger of Easy Street

What weakened David to the point where he fell into sin with Bathsheba (2Sam 11)?

There’s a line in a song “Uncle John’s Band” (Grateful Dead, Workingman’s Dead) that gives us a clue:

“When life looks like easy street, there is danger at your door.” 

Easy street (prosperity and idleness) is dangerous. David’s prosperity gave him the means to feed his flesh. He accumulated wives and possessions against the clear warning God had given to kings in Deuteronomy 17:16-20.

God had crushed all David’s foes. The danger and struggle that had kept David in constant prayer were no longer there. He was so relaxed that he didn’t even go with Joab to finish off the last of the Ammonites. Being idle put David in a position of temptation.

What precautions do you take against the dangers of prosperity and idleness?
