There is an old Keith Green song that I just love. One that casts a somewhat farcical view on such matters. It is called , " So, you wanna go back to Egypt?".
We, like the children of Israel, were born slaves into another kingdom. But, if you are saved in Jesus you are now in the Kingdom of Heaven. The whole salvation transformation goes way beyond just raising your hand, saying a prayer, regularly attending church, and following some rules and regulations for moral conduct. Most civic organizations will ask you to do pretty close to the same thing. God has called his citizens to be transformed.
If you really want to get a handle on this scripture, the word in Romans 12:2 translated transformation is the exact same word that is translated as transfiguration in Matthew 17:2. It is metamorphosis. Literally, to breakthrough a wall/ barrier and transition. On the Mount of Transfiguration ( Transformation), Jesus didn't just become a better person. He was like a butterfly, momentarily transformed.
The Word encourages us to be transformed by the renewing of our minds. This is not Dr. Phil semi-religious psycho-babble, but instead a truth that leads to victory both now, and in the hereafter. As, Christians, not only do our hearts need to change but so do our minds. Let's put it this way, as a faithful follower of Christ, our minds cannot think, reason,or believe the same way that they did from the day that we were saved until now. In, fact, the two should be two very different blobs of grey matter. If not, we will fall prey to dying off in the desert of life as opposed to inheriting the Promised Land.
In the face of the daily supernatural care, provision, and guidance of God in the Wilderness, the first generation of freed Hebrew slaves in 400 years, blew it because of a brainfreeze. They still had a victim mentality. The hopes, trust, and aspirations of a slave. It reminds me of the stories that you hear of people who after losing an amazing amount of weight, get toned, and buffed; yet look in the mirror each day to still see a fat person. Mind sets kill!
But, we don't have to live that way any longer, if you choose. BE TRANSFORMED, by the renewing ( renovation,the rising up in freshness of Heaven, the gaining of God's perspective of your status change) of your mind. The Promised Land is yours to gain!
