Romans 12:2 KJV
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Speaking to the believer, the Apostle Paul, in Romans chapters 1-11, teaches theological truths (note found in the Amplified translation of the Bible). Here, in chapter 12, the Apostle Paul seeks to teach the believer how to apply those truths practically.
When completing my undergraduate and graduate degrees, I often experienced, what I called, information overload. As students, we were provided a plethora of information as a part of our degree plan but, without continuous use of the information, it seemed to get lost among all of the other information we had obtained. Unless we were in a position to continuously use the information provided in a practical manner, the life span of the information was quite short. Sometimes it lasted only as long as to complete the upcoming exam.
I dare say that, as believers, many of us are in like situations as it concerns our spiritual lives. We attend Sunday worship services, midweek Bible studies, conferences and the like and yet, we do not practice what we have learned. Many believers, unbeknownst to them, view the Bible as a history book rather than the book of life that it is. Somehow, we miss the fact that it is the Constitution of the Kingdom of God and as citizens of the Kingdom, we must follow, via practice, its teachings.
Reading the scripture that begins this post, we can determine that transformation is dependent upon mind renewal. In order to renew our minds, it is necessary to fill our minds with the culture of the Kingdom of God, through His word and apply what we have learned.
