'Nature' in the Bible
For since the creation of the world God's invisible attributes his eternal power and divine nature have been understood and observed by what he made, so that people are without excuse.
I am speaking in simple terms because of the frailty of your human nature. Just as you once offered the parts of your body as slaves to impurity and to greater and greater disobedience, so now, in the same way, you must offer the parts of your body as slaves to righteousness that leads to sanctification.
For while we were living according to our human nature, sinful passions were at work in our bodies by means of the Law, to bear fruit resulting in death.
Thank God through Jesus the Messiah, our Lord, because with my mind I myself can serve the Law of God, even while with my human nature I serve the law of sin.
so that the righteous requirement of the Law might be fulfilled in us, who do not live according to human nature but according to the Spirit.
To focus our minds on the human nature leads to death, but to focus our minds on the Spirit leads to life and peace.
That is why the mind that focuses on human nature is hostile toward God. It refuses to submit to the authority of God's Law because it is powerless to do so.
Indeed, those who are under the control of human nature cannot please God.
You, however, are not under the control of the human nature but under the control of the Spirit, since God's Spirit lives in you. And if anyone does not have the Spirit of the Messiah, he does not belong to him.
Consequently, brothers, we are not with respect to human nature, that is under an obligation to live according to human nature.
For if you live according to human nature, you are going to die, but if by the Spirit you continuously put to death the activities of the body, you will live.
After all, if you were cut off from what is naturally a wild olive tree, and contrary to nature were grafted into a cultivated olive tree, how much easier it will be for these natural branches to be grafted back into their own olive tree!
