When I quote this part of Isaiah some people argue that the idea is not in the Bible. Yet there it is. I also have experiential knowledge of the phenomenom referred to in this verse. It is not a fantasy and available to all who call upon the Almighty.

²⁰ Although the Lord gives you the bread of adversity and the water of affliction, your teachers will be hidden no more; with your own eyes you will see them.²¹ Whether you turn to the right or to the left, your ears will hear a voice behind you, saying, “This is the way; walk in it.”  Isiah 30:20-21 NIV

You WILL hear a voice behind you, or almost just a whisper in your head. That still small voice of guidance and wisdom from the King of all kings. A “KNOWING.”

James says when we need wisdom we are to call to Him and He will answer.
