That's not 100% correct and honest.
You look to Exodus 16 to justify your work at the law.
What you may do that is natural, after coming to Christ, is to love people as Christ has loved you. You may extend joy to others that you have received of the Lord. You may be at peace when everything around you is not peaceful.
Even wanting to work at the law in order to be perfect before God is probably a natural reaction to coming to Christ. But it is an act of futility. Because our work at the law doesn't cause us to be perfect. We were much closer to perfection when we gave up our work and asked Christ for His Help and His Work.
Ok I am going to leave the Sabbath for this moment because we are clashing on the law here.
So lets deal with that first. I am going to appeal to logic and common sense biblicaly speaking.
I am going to divide it into points so that I can determine exactly where it is concerning the law that we disagree. So if you disagree with something I say please refer to what point and explain.
1, The purpose of the law:
The purpose of the law is to show sin by that which is good.
Textual support: Rom 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of 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.
1Jn 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
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.
2, The law is not just for Jews as it condemns all both Jew and Gentile.
Textual support:
Rom 3:9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
Rom 3:23 For all have sinned, and come short of the glory of God;
Rom 3:19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
I can supply OT to prove that this was so even in the OT If you would like.
3, If we try to keep the law we fail because we are slaves to the law of sin.
Textual evidence:
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 7:22 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?
Notice the next point comes from verse 24.
4, The law leads us to Christ so that we can be saved.
Textual evidence:
Gal 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
Rom_10:4 For Christ is the end of the law for righteousness to every one that believeth.
5, Jesus came to save us from sin.
Textual evidence:
Mat 1:21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Joh 8:34 Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
Joh 8:35 And the servant abideth not in the house for ever: but the Son abideth ever.
Joh 8:36 If the Son therefore shall make you free, ye shall be free indeed.
1Jn 3:5 And ye know that he was manifested to take away our sins; and in him is no sin.
1Jn 3:6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
1Jn 3:7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
1Jn 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
1Jn 3:9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
So 5 points
