And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God."
Romans 12:1-2 (NKJV)
Sometimes while I am out walking or running, I see people who are walking their dog. But then, something happens where the dog gets upset or a little excited and gets out of control. What is amusing to me is that the people with the dog act surprised that their dog is acting like a dog! They sometimes look around as if they do not know what to do, or that maybe someone else needs to do something, but the person with the dog just needs to take care of their own dog; I often think to myself, it is your dog, you need to control it yourself.
We are a three part being: spirit, soul, and body (1 Thessalonians 5:23). When we are born again, we become a new creation in Christ, spiritually. But even though we are a new creation in Christ, we still have the same body and soul as we did before salvation, and we need to do something with our body and our soul. In Romans 12:1-2, the Bible says that we need to present our body as a living sacrifice and renew our mind, which is a part of the soul. The emphasis here is that we do something with our body and our soul.
It is up to us individually as believers to control our own body and renew our own mind. While other people may help us with this, no one can do it for us. Some people seem to think that if they get enough people praying for them, or if they get into a special meeting, or if someone lays hands on them, everything will be fine. But the Bible clearly tells us that we have to control ourselves. Through learning what the Bible says, and by acting on it with the help of the Holy Spirit, we can control our bodies and renew our minds.
