Do you mean that the law might be in use for something or someone other than a Christian?
If you reject Paul's revelation given by Jesus then you might have missed Galations 3
10¶For as many as are of the works of the law are under the curse: for it is written, Cursed
is every one that continueth not in all things which are written in the book of the law to do them.
11But that no man is justified by the law in the sight of God,
it is evident: for, The just shall live by faith.
12And the law is not of faith: but, The man that doeth them shall live in them.
13¶Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed
is every one that hangeth on a tree:
14That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
(
cf. Gen. 12:1–3 )
15¶Brethren, I speak after the manner of men; Though
it be but a man's covenant, yet
if it be confirmed, no man disannulleth, or addeth thereto.
16Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
17And this I say,
that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
18For if the inheritance
be of the law,
it is no more of promise: but God gave
it to Abraham by promise.
19¶Wherefore then
serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made;
and it was ordained by angels in the hand of a mediator.
20Now a mediator is not
a mediator of one, but God is one.
21¶
Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
22But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
23But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
24Wherefore the law was our schoolmaster
to bring us unto Christ, that we might be justified by faith.
25But after that faith is come, we are no longer under a schoolmaster.
26¶For ye are all the children of God by faith in Christ Jesus.
27For as many of you as have been baptized into Christ have put on Christ.
28There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29And if ye
be Christ's, then are ye Abraham's seed, and heirs according to the promise.
