Definition: Ardentness in Scripture means "vitality or zeal" that involves great devotion, fervor, or enthusiasm for something. It's a strong and unquenchable desire to do something and remains steadfast throughout one's life. The word comes from Hebrew ἐνταδέρειν (inθádèerêi), which translates to "to be keenly anxious." This word emphasizes the intense feelings of devotion or zeal.
