 If you're genuinely saved, you've been made a new creation in Christ. New creation. If you've been genuinely saved, then you have renewed nature. A new heart, the Bible calls it. With that, you have a new heart disposition. Your affections have changed. Your desires have changed. You love the Lord, whereas before, at best, you were uninterested or indifferent. You hate sin. You want to be rid of it. You have the mind of Christ. You've been made a partaker of the divine nature. There's been a transformation in your heart and mind if you're in Christ. But all of that, that new creation, that new disposition, that new heart, that new nature, has been encased, as it were, in your mortal flesh.
