There are those that say works are un-necessary for salvation, and that is not Biblical. Here is one of the references I found:
James Chapter 1: (vs 16-27)
16 -Don't be deceived, my dear brothers.
17 -Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows.
18 -He chose to give us birth through the word of truth, that we might be a kind of firstfruits of all he created.
19 -My dear brothers, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry,
20 -for man's anger does not bring about the righteous life that God desires.
21 -Therefore, get rid of all moral filth and the evil that is so prevalent and humbly accept the word planted in you, which can save you.
22 -Do not merely listen to the word, and so deceive yourselves. Do what it says.
23 -Anyone who listens to the word but does not do what it says is like a man who looks at his face in a mirror
24 -and, after looking at himself, goes away and immediately forgets what he looks like.
25 -But the man who looks intently into the perfect law that gives freedom, and continues to do this, not forgetting what he has heard, but doing it--he will be blessed in what he does.
26 -If anyone considers himself religious and yet does not keep a tight rein on his tongue, he deceives himself and his religion is worthless.
27 -Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world.
Thereore, works do matter, according to the Bible.
