The word complacency usually carries a negative connotation, and the book of Proverbs is no exception.

For the simple are killed by their turning away, and the complacency of fools destroys them.

Proverbs 1:32 (ESV)

The Merriam-Webster Dictionary defines complacency as:

Self-satisfaction especially when accompanied by unawareness of actual dangers or deficiencies.

An instance of usually unaware or uninformed self-satisfaction.

Even AI agrees that complacency is not highly esteemed:

The word «complacency» refers to a feeling of self-satisfaction or contentment, often accompanied by a lack of awareness or concern about potential problems or the need for improvement. It can imply a state of being overly comfortable or smug, sometimes leading to negligence or a lack of effort. In certain contexts, it carries a negative connotation, suggesting a dangerous level of unawareness or inaction.

The good news is that the book of Proverbs offers us help.

But whoever listens to me will dwell secure and will be at ease, without dread of disaster.

Proverbs 1:33 (ESV)

This is wisdom personified and talking to us. Foolish complacency will lead to destruction, but wisdom will keep it far and will make its possessor secure and at ease.
