“Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship.” Romans 12:1 NIV
When you make Jesus Christ Lord of your life, you become what the Bible calls a "new creature". You are not the same person you were before.
You have the nature of God born into you. However it is not enough for you just to have that new nature on the inside, you have to let it take over the outside as well.
Don't expect it to happen automatically. You have to make a decision to bring your body into obedience to the new man within you. Determine to do what Romans 6;12 says and "let not sin reign in your mortal body”.
I know it sounds tough but remember you are not in this alone. You have a Helper
inside you to enable you to carry out that decision. His Name is the Holy Spirit. He's
there to strengthen you. He gives you the power to put sin out of your life and under
your feet.
Make that decisive dedication to your body today, and let that new man that is on the inside of you begin to come out.
Kingdom Blessings!
