The Bible has made it clear that obedience to the law is "works" - Paul states clearly that works are "of the law".
For no human being will be justified in his sight by works of the law, since through the law comes knowledge of sin (Rom 3:20).
For we hold that a man is justified by faith apart from works of law (Rom 3:28).
Yet we know that a man is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ, and not by works of the law, because by works of the law shall no one be justified (Gal 2:16).
Let me ask you only this: Did you receive the Spirit by works of the law, or by hearing with faith? (Gal 3:2)
Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith? (Gal 3:5)
For all who rely on works of the law are under a curse. For it is written, ‘Cursed be every one who does not abide by all things written in the book of the law, and do them’ (Gal 3:10).
Contrast that against the Mormon church's false gospel which directly contradicts what the Bible says about works of the Law by saying "... all mankind may be saved, by obedience to the laws and ordinances of the Gospel." That's Satan's own lie - telling people that they can be saved in any part by their own works because it goes directly against the True Gospel of Christ.
You misunderstand the scriptures. While it is true that we are not justified by works, it is very clear that we can't be saved without them either. In fact we are saved by grace after all we can do. This fact is made very clear in the Bible:
(New Testament | 1 Peter 3:21)
21 The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
(New Testament | Romans 3:31)
31 Do we then make void the law through faith? God forbid: yea,
we establish the law.
(New Testament | Romans 6:1 - 18)
1 WHAT shall we say then?
Shall we continue in sin, that grace may abound?
2 God forbid.
How shall we, that are dead to sin, live any longer therein?
3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that
henceforth we should not serve sin.
7 For he that is dead is freed from sin.
8 Now if we be dead with Christ, we believe that we shall also live with him:
9 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
10 For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
12
Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
13 Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
14 For sin shall not have dominion over you: for ye are not under the law, but under grace.
15 What then?
shall we sin, because we are not under the law, but under grace? God forbid.
16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.
18 Being then made free from sin,
ye became the servants of righteousness.
(New Testament | 2 Peter 2:20 - 22)
20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
21
For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22 But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
