Wisdom from self is filled with indecision, questioning, impulses, even hesitating. At best a shallow decision forward is finally made born out of your best guess. Wisdom learned through spending time with God is orderly, definitive, methodical, and a process of understanding. Then any decision that is made is done with confidence in the Holy Spirit within, even at a moments notice. It is a solid knowing, a supernatural feeling, and a decision you know you can defend without a shadow of a doubt.
Wisdom can miraculously heal your mind so clearly that self made plans are no longer needed or sought after. It is a kind of freedom. It can actually take your fear of failure, running out of money, becoming homeless, jobless, illness, death, and turn it into peace when you surrender it all to God.
You are the God who works wonders; you have made known your might among the peoples. Psalm 77:14
