Due to disbelief when faced with difficulties, the Hebrews were once again disapproved in their faith. Instead of believing, they sought someone to blame for their problems – in this case, Moses, who was almost stoned.

Thus, they showed that they were not prepared to become a nation.

Note that, just as obedience demonstrates faith, disbelief reveals a perverse heart.

Struggles exist not to lead us to sin, but to lead us to honor the Almighty God with our trust.
