this is why I ask this question tagged at the bottom of all my post........
Not only so, but Paul illustrates that the governing inclination of man has been eternally changed toward righteousness by regeneration. The issue in a child of God in regard to sin is the power of indwelling sin over the will:
Rom. 7:17
Now then it is no more I that do it, but sin that dwelleth in me.
18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
19 For the good that I would I do not: but the evil which I would not, that I do.
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
21 I find then a law, that, when I would do good, evil is present with me.
22 For I delight in the law of God after the inward man:
A true child of God sins in spite of his hatred of sin because the governing disposition toward righteousness is POWERLESS to overcome indwelling sin.
"
TO WILL IS PRESENT WITH ME; but HOW to PERFORM that which is good I find not"
A true child of God CANNOT WILL to reject Jesus Christ - it is impossible because the governing disposition of the saved man is created in true holiness and righteousness and what is born of God "cannot sin" BECAUSE OF the seed which abides in him. This "seed" is the REGENERATE LIFE or the RENEWED NATURE which controls the governing inclination of man toward holiness and righteousness.
A born again man sins MORE THAN HE WANTS TO and even in sin his inward man HATES what he is doing.
For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
This is the inward struggle within only a true child of God for only a true child of God has TWO NATURES in combat with each other that produce a WRETCHED internal state of affairs as long as the child of God attempts to deal with sin according to his own power.
The true child of God will eventually have the victory over indwelling sin because Jesus Christ will deliver them eventually:
24 O wretched man that I am! who shall deliver me from the body of this death? 25 I thank God through Jesus Christ our Lord.
However, there is no full deliverance in this life from the presence of indwelling sin and so "now" this struggle continues:
So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Only physical death or transformation delivers the saints from this indwelling power of corruption (1 Cor. 16:52-55).
However, there is NOW partial experiential deliverance from the condemnation and power of indwelling sin by Jesus Christ when the child of God does not walk "after" the flesh but "after" the Spirit of God.
The lost man is "IN the flesh" but the saved man can walk "AFTER" the flesh when he attempts to deal with indwelling sin according to his own will power. Those who are "IN" the flesh cannot please God but those "IN" the Spirit can please God but only through the power of the indwelling Spirit of God. It is through the power of the indwelling Spirit of God they can mortify or put to death the deeds of the flesh.
This internal struggle has nothing to do with success or failure to enter heaven but with success and failure for present victory over indwelling sin. The true experience of a child of God is a mixture of Romans 7:14-25 and Romans 8:9-13.
However, it is impossible for a child of God to ever choose to reject Jesus Christ and turn anti-Christ because the governing inclination within man is controlled by the inward man which is created in true holiness and righteousness. Sin occurs in a child of God ONLY due to a lack of POWER by the inward man to enforce its righteous inclination and so even in the act of sin there is a holy hatred for what the saint is doing by INWARD coercion/power of indwelling sin:
For that which I do [sin] I allow not: for what I would,[righteousness] that do I not; but what I hate, [sin] that do I.
Hence, the only professing Christians that can turn anti-Christ, reject God and apostatize from their profession are lost professors:
1 Jn. 2:19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
Not a single one that the Father gives to the Son to save will fail to come to the Son and not a single one that comes to the Son in faith will ever be lost but that individual will be raised unto eternal life:
Jn. 6:37
All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
39 And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
However, presently we have a great PROFESSING KINGDOM on earth mixed with "tares" and the true "seed" of the kingdom and apostasy and love for sin are some visible signs of false professors.
