That is why one of the characteristics of the word is to be light in the middle of darkness.
The psalmist David put it this way:
Psalm 119: 105
"Your word is a lamp to my feet,
And a light to my path ".
(RVR1960)
Here David compares the word of God to a lamp that illuminates our path and directs each of our steps, in addition to providing wisdom to our future plans.
He also declares that all his word is eternal and is true
Psalm 119: 160
160 The sum of your word is truth,
And eternal is all judgment of your righteousness.
(RVR1960)
In this way we can understand that the word of God is the surest way to live both for success and for eternal prosperity that no one else knows how to give but only God.
Everything we do in life will be added to God's justice because no one will be able to escape from it, for this reason God grants us the privilege of looking for him while he can be found in order to be able to access his grace and enjoy his blessings that are real and eternal.
You may or may not believe in God, you may please or you may not live your life your way if you want but remember that of all these things God will judge us fairly.
The word of God is the sum of all truth and guiding us by it will give us a practical and fruitful life.
