That's problem I'm only good when the question when it's logic based.
I understand completely. I'm the same way. I tend to excel when I am familiar with the boundaries that have been set before me. That's why it is critical that we read the bible everyday.
However, in the past, I had struggled with habitual sin and did everything within my power to stop only to fail time after time after time. It wasn't until I was able fully comprehend, both in my mind and in my heart, what exactly Jesus accomplished on the cross that day that I was delivered from old sinful habits.
I believe that there are a lot of prime examples here on CC of people who know the word of God extensively yet do not truly know the heart of God. You can see it both in their words and in deeds. One can have all the knowledge in the world, yet if he knows not love than such knowledge is useless. A prime biblical example of this is King Solomon.
