You have tested me and you find nothing -- Psalm 17

Psalm 17:3 You have tried my heart; You have visited me by night; You have tested me and you find nothing; I have purposed that my mouth will not transgress.

What an awesome testimony! David dared to say those words in the midst of persecusion and adversity. When hated blatantly and chased after day and night, he remained his heart pure and in love. He refused to place judgement by himself in his ways upon his enemies, rather he asked the Lord for His justice in His time. (verse2 Let my judgement come forth from Your presence.)

This had to an outcome of being in the wilderness.
