Why is it that not everyone worships God?

Read Job 12.

To Zophar's accusations, Job responded with three chapters of defense.  In the banter regarding wisdom and endeavoring to search out the meaning of this real life situation, Job first expounded on the true source of wisdom, all understanding, and ultimate control.

God's power and wisdom are immediately knowable to everyone.

1. All of humanity should know the LORD.
Job did not possess a Bible.  He had no theological training.  So, how could he have such understanding about God?
"For what can be known about God is plain to them, because God has shown it to them."
(Romans 1:19)

How has God shown Himself to everyone?

2. All of nature could tell us.  vv.7-10
Job offered that if the beasts, birds, plants and fish could talk they would declare God's wisdom and power.
"For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made.  So they are without excuse."
(Romans 1:20)

Then, why is it that not everyone worships Him?

3. All of life experience should tell us.  vv.11-12
Daily God is at work shaping our lives for His purposes.  Believers trust Him and look for His faithfulness.  Others reject God's plan and go their own way to their detriment.
"For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.  Claiming to be wise, they became fools..."
(Romans 1:21-22)

"The fear of the LORD is the beginning of knowledge; fools despise wisdom and instruction."
(Proverbs 1:7)
