Scriptures Referenced in This Episode:

“Job, are you the one who gives the horse its strength

    or puts a flowing mane on its neck?

Do you make the horse jump like a locust?

    It scares people with its proud snorting.

It paws wildly, enjoying its strength,

    and charges into battle.

It laughs at fear and is afraid of nothing;

    it does not run away from the sword.” Job 39:19-22 (NCV)

“Then God said, ‘Let us make human beings in our image and likeness. And let them rule over the fish in the sea and the birds in the sky, over the tame animals, over all the earth, and over all the small crawling animals on the earth.’

So God created human beings in his image. In the image of God he created them. He created them male and female. God blessed them and said, “Have many children and grow in number. Fill the earth and be its master. Rule over the fish in the sea and over the birds in the sky and over every living thing that moves on the earth.” Genesis 1:26-28 (NCV)

“You put them in charge of everything you made.

    You put all things under their control:

all the sheep, the cattle,

    and the wild animals,

the birds in the sky,

    the fish in the sea,

    and everything that lives under water.

Lord our Lord,

    your name is the most wonderful name in all the earth!” Psalm 8:6-9 (NCV)
