What are the key themes in Michelle Palmer's book 'Be Still & Know'?

From what I share online, Be Still & Know centers on a few recurring themes:

1. Pausing in the middle of a noisy life to be still—emotionally, mentally, and spiritually
2. Trusting God’s presence and care in everyday circumstances
3. Finding comfort and strength in Scripture
4. Letting go of worry and control, and resting in God’s character

Is there a particular area—like anxiety, trust, or daily habits—you’re most interested in?
