“Born This Way” or “Born Again”?--Can the “New Man” Continue to Live by His “Old Nature”?

​John 3
1 Now there was a Pharisee, a man named Nicodemus who was a member of the Jewish ruling council. 2 He came to Jesus at night and said, “Rabbi, we know that you are a teacher who has come from God. For no one could perform the signs you are doing if God were not with him.”
3 Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.”
4 “How can someone be born when they are old?” Nicodemus asked. “Surely they cannot enter a second time into their mother’s womb to be born!”
5 Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. 6 Flesh gives birth to flesh, but the Spirit gives birth to spirit. 7 You should not be surprised at my saying, ‘You must be born again.’ 8 The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.”
Galatians 5
13 You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh; rather, serve one another humbly in love. 14 For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.” 15 If you bite and devour each other, watch out or you will be destroyed by each other.
16 So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17 For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want. 18 But if you are led by the Spirit, you are not under the law.
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery; 20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
22 But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control. Against such things there is no law. 24 Those who belong to Christ Jesus have crucified the flesh with its passions and desires. 25 Since we live by the Spirit, let us keep in step with the Spirit. 26 Let us not become conceited, provoking and envying each other.
Hebrews 10
26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, 27 but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. 28 Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. 29 How much more severely do you think someone deserves to be punished who has trampled the Son of God underfoot, who has treated as an unholy thing the blood of the covenant that sanctified them, and who has insulted the Spirit of grace? 30 For we know him who said, “It is mine to avenge; I will repay,” and again, “The Lord will judge his people.” 31 It is a dreadful thing to fall into the hands of the living God.
1 John 3
1 See what great love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him. 2 Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is. 3 All who have this hope in him purify themselves, just as he is pure.
4 Everyone who sins breaks the law; in fact, sin is lawlessness. 5 But you know that he appeared so that he might take away our sins. And in him is no sin. 6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8 The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9 No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God. 10 This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.
Romans 6
1 What shall we say, then? Shall we go on sinning so that grace may increase? 2 By no means! We are those who have died to sin; how can we live in it any longer? 3 Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? 4 We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.
5 For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. 6 For we know that our old self was crucified with him so that the body ruled by sin might be done away with, that we should no longer be slaves to sin— 7 because anyone who has died has been set free from sin.
8 Now if we died with Christ, we believe that we will also live with him. 9 For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him. 10 The death he died, he died to sin once for all; but the life he lives, he lives to God.
11 In the same way, count yourselves dead to sin but alive to God in Christ Jesus. 12 Therefore do not let sin reign in your mortal body so that you obey its evil desires. 13 Do not offer any part of yourself to sin as an instrument of wickedness, but rather offer yourselves to God as those who have been brought from death to life; and offer every part of yourself to him as an instrument of righteousness. 14 For sin shall no longer be your master, because you are not under the law, but under grace.
15 What then? Shall we sin because we are not under the law but under grace? By no means! 16 Don’t you know that when you offer yourselves to someone as obedient slaves, you are slaves of the one you obey—whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness? 17 But thanks be to God that, though you used to be slaves to sin, you have come to obey from your heart the pattern of teaching that has now claimed your allegiance. 18 You have been set free from sin and have become slaves to righteousness.
19 I am using an example from everyday life because of your human limitations. Just as you used to offer yourselves as slaves to impurity and to ever-increasing wickedness, so now offer yourselves as slaves to righteousness leading to holiness. 20 When you were slaves to sin, you were free from the control of righteousness. 21 What benefit did you reap at that time from the things you are now ashamed of? Those things result in death! 22 But now that you have been set free from sin and have become slaves of God, the benefit you reap leads to holiness, and the result is eternal life. 23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

There are many more passages on this topic. Also there are many places which tell us that we will still fall short and sin after we are saved, so please don’t read this as “those who are not perfect are not really saved.” There is a difference between falling into temptation and intentionally, habitually living in sin and making that sin part of your identity. Speaking personally here, I would at one time in my life describe myself as a liar. It was my instinct to lie, sometimes even when I didn’t need to. I would also describe unregenerate self as being controlled by anger, being manipulative and taking advantage of others, just as a few examples. Unfortunately I also thought I was a Christian during much of this time because I “said the magic words” when I was a child (prayed the Sinner’s Prayer) and had an intellectual knowledge of what Jesus did on the cross for me. I could probably even explain the gospel to someone else and point them to the Bible verses that told them about what they must do to be saved, but my life was empty of any evidence that I myself had been saved because I continued to be controlled by my flesh and my sin nature. It was not until I came to grips with these passages and others that I realized that I could not truly be saved if I continued to live in sin to the point where myself and other identified me by my sin nature. I could quote all the Scripture I knew and sing all the Christian songs and hymns that I knew, but ultimately I was still a caterpillar that had never been transformed into a butterfly.

How about you? Would you say that you have gone through a metamorphosis whereby those who knew you before no longer recognize you? Are you looking for that kind of transformation? There is only one way for that to happen and that is through making Jesus not only Savior, but Lord of your life and to accept that by faith He has the power to put your sin nature to death and to give you a new nature and to give you a new identity so that you can live out the new, eternal life that only He can give you. If you’d like to know more about this, please let me know as I’d be happy to speak with you about it.
