This passage starts and ends with pride versus humility. I wonder about some of the verses in between:
The heart of the righteous ponders how to answer,
but the mouth of the wicked pours out evil things.
How does this manifest in pride? I think the teacher here is saying to me that my tendency to be brusque and impatient with people comes from my pride. And it’s sin. Certainly I say hateful or hurtful things more often when my pride is running ahead of me — when I am either impatient for someone to get to the point or when I want to show off my knowledge. Either way, I’m not pondering how to answer, and what comes out of it is wickedness.
When you send forth your Spirit, they are created,
and you renew the face of the ground.
Psalms 104: 30
The LORD creates not (only) once at the beginning of time, but moment to moment throughout all His creation. When His face is hidden, all things turn to dust. Praise God that He continues to create us!
The Old Testament is (among other things) the story of God keeping His promises.
