The images of verses 6-9 are awe-inspiring, especially as we slow down to picture each one. These verses compare to Genesis chapters 1 and 2, God as Creator. He breathed, and the Earth was made, as was everything in it. He breathed the stars into being (v. 6) - and yet, His creation of us is even more intimate. When you doubt your worth or your significance, when you doubt if you are loved, remember that the Creator of those stars that fill you with wonder crafted you specifically.
We admire the ocean for its power and beauty. Its waves can easily overpower us, and yet God gathers the oceans into jars.
