There are Biblical examples of these types of people. In these two categories, Saul of Tarsus leaps to mind. Saul was convinced beyond a shadow of a doubt that arresting and executing disciples of Christ was a godly and glorious pursuit. He was good at it. He was completely focused on his goal. So much so that Stephen’s incisive explanation of the Gospel made no dent or difference in Saul’s thinking or goals. So when he was proceeding down to Damascus to pursue his goals, the Lord slapped him up side of the head with the proverbial 2x4. It took that, plus a few days of physical blindness, to open his spiritual eyes. Christ knew that it would take that type of intervention to get Saul’s attention.
There are other examples to which we could point. As I said I am not certain of the global nature of the observation, but it makes me think. It makes me think that I want to be more open to the direction of the Lord than Saul was. I would like to avoid that level of pain if possible. If it is true that God deals with me according to my nature, I would like to have a nature that learns quickly; one that is responsive to His prompting and leading.
What nature are you presenting to Him?
