This is not a secret!

 Many are the sorrows of the wicked, but steadfast love surrounds the one who trusts in the Lord. Be glad in the Lord, and rejoice, O righteous, and shout for joy, all you upright in heart!

Psalm 32:10-11 (ESV)
 
Those who ignore God can only find peace and joy in the temporal and, therefore, wear themselves out constantly trying to accommodate their temporal desires. When you ignore God, you ignore purpose. When you ignore God, there is no chance for you ever to find significance and security.
 
One can watch the Godless, see evidence of their struggle, and contrast their lives with the Godly. Those who trust in God see a true joy in the journey. Those who trust in anything else see the journey as a possible threat to their joy.
 
Steadfast, reliable, steady. These are good words that describe those whose lives are anchored in the truth of God's Word.
 
This is not a secret; it has been shouted from the mountains for years. However, it is mainly ignored, and today, when you ignore God, you ignore purpose. When you ignore God, there is no chance for you ever to find significance and security.
