No, faith does not discard the necessity to obey the commandments of God.
The real issue here seems to be overlooked- that is, the definition of faith. Let's get to the bottom of the matter.
Luther again-
Faith is not what some people think it is. Their human dream
is a delusion. Because they observe that faith is not followed by
good works or a better life, they fall into error, even though they
speak and hear much about faith. ``Faith is not enough,'' they
say, ``You must do good works, you must be pious to be saved.''
They think that, when you hear the gospel, you start working,
creating by your own strength a thankful heart which says, ``I
believe.'' That is what they think true faith is. But, because
this is a human idea, a dream, the heart never learns anything
from it, so it does nothing and reform doesn't come from this
`faith,' either.
Instead, faith is God's work in us, that changes us and gives
new birth from God. (John 1:13). It kills the Old Adam and makes us
completely different people. It changes our hearts, our spirits,
our thoughts and all our powers. It brings the Holy Spirit with
it. Yes, it is a living, creative, active and powerful thing, this
faith. Faith cannot help doing good works constantly. It doesn't
stop to ask if good works ought to be done, but before anyone
asks, it already has done them and continues to do them without
ceasing. Anyone who does not do good works in this manner is an
unbeliever. He stumbles around and looks for faith and good
works, even though he does not know what faith or good works are.
Yet he gossips and chatters about faith and good works with many
words.
Faith is a living, bold trust in God's grace, so certain of
God's favor that it would risk death a thousand times trusting in it.
Such confidence and knowledge of God's grace makes you happy,
joyful and bold in your relationship to God and all creatures. The
Holy Spirit makes this happen through faith. Because of it, you
freely, willingly and joyfully do good to everyone, serve
everyone, suffer all kinds of things, love and praise the God who
has shown you such grace. Thus, it is just as impossible to
separate faith and works as it is to separate heat and light from
fire!Therefore, watch out for your own false ideas and guard
against good-for-nothing gossips, who think they're smart enough
to define faith and works, but really are the greatest of fools.
Ask God to work faith in you, or you will remain forever without
faith, no matter what you wish, say or can do.
So, the issue as to whether or not Abraham would have been justified if he had not obeyed God is a nonsense- because he was responding to God with the faith he already had. He would not have even considered sacrificing Issac unless he had the faith to trust God.
Luther- (from his commentary on Galatians, Ch 3- I've edited it a lot too)
Objections to the Doctrine of Faith Disproved
"Here we shall take the time to enter upon the objections which our opponents raise against the doctrine of faith. There are many passages in the Bible that deal with works and the reward of works which our opponents cite against us in the belief that these will disprove the doctrine of faith which we teach......In the eleventh chapter of the Epistle to the Hebrews we find a catalogue of various works and deeds of the saints of the Bible. David, who killed a lion and a bear, and defeated Goliath, is mentioned. In the heroic deeds of David the scholastic can discover nothing more than outward achievement. But the deeds of David must be evaluated according to the personality of David. When we understand that David was a man of faith, whose heart trusted in the Lord, we shall understand why he could do such heroic deeds......Before David could achieve a single heroic deed he was already a man beloved of God, strong and constant in faith.
Of Abel it is said in the same Epistle: "By faith Abel offered unto God a more excellent sacrifice than Cain." When the scholastics come upon the parallel passage in Genesis 4:4 they get no further than the words: "And the Lord had respect unto Abel and to his offering." "Aha!" they cry. "See, God has respect to offerings. Works do justify." With mud in their eyes they cannot see that the text says in Genesis that the Lord had respect to the person of Abel first. Abel pleased the Lord because of his faith. Because the person of Abel pleased the Lord, the offering of Abel pleased the Lord also. The Epistle to the Hebrews expressly states: "By faith Abel offered unto God a more excellent sacrifice."
In our dealings with God the work is worth nothing without faith, for "without faith it is impossible to please him." (Hebrews 11:6.) The sacrifice of Abel was better than the sacrifice of Cain, because Abel had faith.........."Do this and thou shalt live," means: First have faith in Christ, and Christ will enable you to do and to live.
.......Abraham was accounted righteous because faith pervaded his whole personality and his every action....
When you read how the fathers, prophets, and kings accomplished great deeds, remember to explain them as the Epistle to the Hebrews accounts for them: "Who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions." (Hebrews 11:33.) In this way will we correctly interpret all those passages that seem to support the righteousness of works. The Law is truly observed only through faith. ...
Supposing that this explanation will not satisfy the scholastics, supposing that they should completely wrap me up in their arguments (they cannot do it), I would rather be wrong and give all credit to Christ alone. Here is Christ. Paul, Christ's apostle, declares that "Christ hath redeemed us from the curse of the law, being made a curse for us." (Gal. 3:13.) I hear with my own ears that I cannot be saved except by the blood and death of Christ. I conclude, therefore, that it is up to Christ to overcome my sins, and not up to the Law, or my own efforts. If He is the price of my redemption, if He was made sin for my justification, I don't give a care if you quote me a thousand Scripture passages for the righteousness of works against the righteousness of faith. I have the Author and Lord of the Scriptures on my side. I would rather believe Him than all that riffraff of "pious" law workers. "
