is,

Wisdom in action.
Prudence is cautious, reserved, quick to understand, ready to discern and distinguish ideas, and to separate the truth from falsehood.
"Prudence implies more caution and reserve than wisdom, or is exercised more in forseeing and avoiding evil, than in devising and executing that which is good..."
Noah Webster, 1828

See then that ye walk circumspectly, not as fools, but as wise, Redeeming the time, because the days are evil.
Ephesians 5:15-16
