The Heart: God: Searched

As for you, Solomon my son, know the God of your father and serve Him wholeheartedly and with a willing mind, for the LORD searches every heart and understands the intent of every thought. If you seek Him, He will be found by you; but if you forsake Him, He will reject you forever.

I, the LORD, search the heart; I examine the mind to reward a man according to his way, by what his deeds deserve.
