The answer is: Psalms

Ps 59:8

The only time Scripture notes God chuckling might come as a surprise to some— it’s found in Psalm 59:8! This verse reveals that divine humor exists even amid remarkably intense scenarios. The imagery here is fascinating because it reflects how God, seeing the wrongdoings and mischief of humanity, can't help but find the absurdity in it all. Much like when we witness a child’s bold but futile mischief, transcendent humor emerges in God’s divine perception of human folly.

In Hebrew, the phrase implies a range of emotions; laughter can reflect joy or derision. Traditionally, many interpretations describe this laugh as a mocking sound aimed at the wicked. Isn't it intriguing to think that even the Creator of the universe possesses a sense of humor, using laughter as a way to view a world riddled with chaos?

The theme resonates throughout the Scriptures, whether from Abraham learning of his impending fatherhood in old age with a hearty belly laugh (Genesis 17:17), or Sarah snickering from within her tent. It’s a testimony to the organic relationship shared between the Divine and humanity — it’s inherently personal, punctuated with shared human experiences such as laughable moments.

So, when considering the laughter of God, it invites reflection—not only upon divine justice but on the affectionate, albeit sometimes stern, parental aspect of God's nature, engaged with us even in lightheartedness. After all, laughter can be the best medicine in our heavy moments too!
