Disciples of Jesus are always going through the process of renewing their minds. The apostle Paul said we should be “transformed by the renewing of your mind” (Romans 12:2). Renewing your mind means much more than replacing dreadful habits with better ones, old habits with new ones. The renewing is a restoring to what God originally intended. When Christ returns, He will restore all things to their original design.
All of nature, all the animals, birds of the sky, and fish of the sea will be resplendent in a majesty we have never seen. They will be renewed into what they were created to be. It will be the same with humanity. God makes all things new (Revelation 21:5). Renewing your mind then is to be a part of what God is doing in the world. It is to be a part of His redemption story.
