To the unbeliever or agnostic: "Will you condemn me that you may be in the right?" (Job 40:8)

These words were directed to Job by God. Although he believed in God, he questioned God's ways. For the unbeliever or agnostic who questions God's existence, these words also have resonance:

38 Then the Lord answered Job out of the whirlwind and said:

2 “Who is this that darkens counsel by words without knowledge?
3 Dress for action[a] like a man;
    I will question you, and you make it known to me.

4 “Where were you when I laid the foundation of the earth?
    Tell me, if you have understanding.
5 Who determined its measurements—surely you know!
    Or who stretched the line upon it?
6 On what were its bases sunk,
    or who laid its cornerstone,
7 when the morning stars sang together
    and all the sons of God shouted for joy?

8 “Or who shut in the sea with doors
    when it burst out from the womb,
9 when I made clouds its garment
    and thick darkness its swaddling band,
10 and prescribed limits for it
    and set bars and doors,
11 and said, ‘Thus far shall you come, and no farther,
    and here shall your proud waves be stayed’?

For those who doubt, Read Job in the Old Testament particularly Chapter 38 through 41.
