exhaustible?

Whoever watches the wind will not plant;
whoever looks at the clouds will not reap.

As you do not know the path of the wind,
or how the body is formed in a mother's womb,
so you cannot understand the work of God,
the Maker of all things.

Sow your seed in the morning,
and at evening let not your hands be idle,
for you do not know which will succeed,
whether this or that,
or whether both will do equally well.

- Ecclesiastes 11:4-6

Why do you say, O Jacob,
and complain, O Israel,
"My way is hidden from the LORD;
my cause is disregarded by my God"?

Do you not know?
Have you not heard?
The LORD is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom.

He gives strength to the weary
and increases the power of the weak.

- Isaiah 40:27-29

Jesus answered, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit. You should not be surprised at my saying, 'You must be born again.' The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit."

- John 3:5-8
