Those who are teaching the law of Moses, Feast days & dietary for eternal life are false!

Gal_2:4  And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: Act 13:38  Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins:  Act 13:39  And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.  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.  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. Gal 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.  Gal 3:11  But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
