Final answer:
Packer's observation that no one would imagine a jealous God contrasts with biblical references to God's jealousy and highlights the disconnect between historical depictions and modern perceptions of divinity.
Step-by-step explanation:
Packer's point that "no one would imagine a jealous God" can be interpreted as a commentary on how humanity perceives the divine, in contrast to historical and biblical descriptions of a deity with human-like emotions such as jealousy.
In the Bible, particularly in Exodus 20:5-6, God is explicitly described as a "jealous God," punishing sin across generations. Yet, Packer suggests a dissonance between this portrayal and the modern conceptualization of a deity, or the lack thereof, as a being that would not be concerned with human notions like jealousy. This reflects the changing views of the divine, where God is either believed to be beyond human attributes or where humankind's understanding and construction of God are so varied that a singular attribute such as jealousy seems unfitting.
Packer's observation touches upon the broader philosophical and theological debates regarding the nature of God, human interpretations thereof, and how these interpretations affect religious belief and practice.
