“Who has put wisdom in the mind? or who has given understanding to the heart?” Job 38:36

Wisdom and understanding come from God. We so often think it is our own doing. Not so. God is the one who is in control of all things and gives what He desires to whom He desires. You can not thwart the plans of God.

God knows you better than anyone and has made you for a special purpose. You can rest in His grace.  

Psalm 139:1-6

“O Lord, You have searched me and known me. You know my sitting down and my rising up; You understand my thought afar off. You comprehend my path and my lying down, And are acquainted with all my ways. For there is not a word on my tongue, But behold, O Lord, You know it altogether. You have [b]hedged me behind and before, And laid Your hand upon me. Such knowledge is too wonderful for me; t is high, I cannot attain it.”
