Romans 7:13-20 NKJV ( Law Cannot Save from Sin )
Has then what is good become death to me? Certainly not! But sin, that it might appear sin, was producing death in me through what is good, so that sin through the commandment might become exceedingly sinful. 14 For we know that the law is spiritual, but I am carnal, sold under sin. 15 For what I am doing, I do not understand. For what I will to do, that I do not practice; but what I hate, that I do. 16 If, then, I do what I will not to do, I agree with the law that it is good. 17 But now, it is no longer I who do it, but sin that dwells in me. 18 For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find. 19 For the good that I will to do, I do not do; but the evil I will not to do, that I practice. 20 Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me.
Romans 8:6-8 NKJV ( Free From Indwelling Sin )
For to be carnally minded is death, but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. 8 So then, those who are in the flesh cannot please God.
I Corinthians 3:1-4 NKJV ( Sectarianism Is Carnal )
And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babies in Christ. 2 I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; 3 for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men? 4 For when one says, “I am of Paul,” and another, “I am of Apollos,” are you not carnal?
II Corinthians 10:1-6 NKJV ( The Spiritual War )
Now I, Paul, myself am pleading with you by the meekness and gentleness of Christ—who in presence am lowly among you, but being absent am bold toward you. 2 But I beg you that when I am present I may not be bold with that confidence by which I intend to be bold against some, who think of us as if we walked according to the flesh. 3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled.
