Vulnerability: (According to Oxford Dictionary) The quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally.
This verse shows my vulnerability with God. I can think I have pure motives, but He knows my heart. That can feel scary, or be comforting.
Scary in that, if I am not allowing myself to stay connected to God, my motives can become tainted, which disconnects me from Him. Leaving my heart open to harm from people or circumstances. Comforting in that, when my motives are pure, it allows me to have a deeper relationship with God. Allowing my heart greater protection.
