Hi yuehan
Quote: The issue of whether a Christian has one righteous nature or two natures (an old sinful nature, and a new righteous nature.
We must consider how we are made.
1 Thess 5:23 means "all of us." When Paul prays, "may your whole spirit and soul and body be kept blameless," he means, "your whole being."
Spirt and Soul and Body.
In Heb 4:12 the author is highlighting the unmatched power of the Word of God. It is so uniquely powerful that it can even pierce "the division of soul and of spirit, of joints and of marrow," and discern "the thoughts and intentions of the heart."
Spirit and Soul and Body.
When you got born again, your Spirit was made new.
Quote: Of course, we still have to contend with sin in the flesh, but neither sin nor flesh define who we truly are.
That is a correct statement, but what is the Flesh?
Let's look at the works of the flesh; Paul speaks about the works of the flesh.
Gal 5:19”“21 speaks of the works of the flesh, saying they are "evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these."
Where do these works of the flesh come from? Jesus gives us the answer.
Matt 15:18-20 But what comes out of the mouth proceeds from the heart, and this defiles a person. For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. These are what defile a person.
As has been well said, the heart of the human problem is the problem of the human heart. Not the blood pumping vessel that is the concern of your cardiologist, but the seat of your personality that is the concern of the Gospel.
Jesus teaches us that there is something far more fundamental to our sinfulness than the actual sins we commit. Our sins do not make us sinful. Rather, we commit sins because, at the very center of our lives, we are sinful. Sin has invaded the inner recesses of our personalities.
What is the heart?
"Heart" (Hebrew lebab/leb [b'bel], Gk. kardia [kardiva]) occurs over one thousand times in the Bible, making it the most common anthropological term in the Scripture. It denotes a person's center for both physical and emotional-intellectual-moral activities;
Heart ”“ your mind, your will, and emotions.
I appeal to you, therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
Paul is speaking to Christians in Rome (Brothers) he says be transformed by the renewal of your mind. (Heart)
Paul is speaking to Ephesians Christians
Ephesians 4:22-24 to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness of God in true righteousness and holiness.
Let me ask put off the old self; be renewed in the spirit of your minds (heart) and put on the new self.
In your mind, your will and emotions, (Heart) Christ must be put on.
That is why Paul says I am crucified with Christ, because his mind, will and emotions were renewed.
