How can a believer who walks in love by the Spirit of God commit murder? Love alone fulfills the law and if one has hate in their heart they are already condemned by the law as a murderer... That's the purpose of the law ...to make all guilty before God so that they would turn to Christ and receive the Spirit of God and have the law upon their heart. I want all people to obey all laws that agree with God.
I have heard this before many times and it sounds just wonderful, the problem is that it is unscriptural...
Rom 7:12 Wherefore the law is holy, and the commandment holy, and just, and good.
Rom 7:13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful.
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that it is good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 7:18 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.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
Paul still fought his human nature twenty some years AFTER his conversion.
Jas 4:5 Do ye think that the scripture saith in vain, The spirit that dwelleth in us lusteth to envy?
Jas 4:6 But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.
John addresses the fact that the saints, the believers, the converted (whatever you wish to call them) still sin and need Christ's sacrifice...
1Jn 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
1Jn 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
1Jn 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
1Jn 2:2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
Paul acknowledged that he still fought that battle...
1Co 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.
1Co 9:25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
1Co 9:26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
1Co 9:27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
As far as the purpose of the Law? It is to show right and wrong...
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
1Jn 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
The Law defines sin and without Law there is no sin...
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
Rom 4:15 Because the law worketh wrath: for where no law is, there is no transgression.
Rom 5:13 (For until the law sin was in the world: but sin is not imputed when there is no law.
So if you wish to declare a person a legalist for obeying God, that is your prerogative, but as for me and my house...
