Could someone explain to me and maybe give me a few verses on how works are necessary for salvation?
I think that part of the problem you may have in understand the necessity of works is that you may be thinking of the works of the Mosaic Law, which cannot save, with the works of the Spirit in the Believers; perhaps I might be able to help:
8If you really keep the royal law found in Scripture, “Love your neighbor as yourself,” you are doing right. 9But if you show favoritism, you sin and are convicted by the law as lawbreakers. 10For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. 11For he who said, “Do not commit adultery,” also said, “Do not murder.” If you do not commit adultery but do commit murder, you have become a lawbreaker. (St. James 2:8-11)
Clearly there is a difference between the works which reflect Salvation and the works of the Law.
14What good is it, my brothers, if a man claims to have faith but has no deeds? Can such faith save him? 15Suppose a brother or sister is without clothes and daily food. 16If one of you says to him, “Go, I wish you well; keep warm and well fed,” but does nothing about his physical needs, what good is it? 17In the same way, faith by itself, if it is not accompanied by action, is dead. (St. James 2:14-17)
St. James statement is very succinct: Faith requires a physical demonstration of the “royal Law:” Love! When queried Jesus stated that there is one Commandment which is the first (Love the Lord God) and a second which is of secondary importance (Love your neighbor as yourself) and that in these two Commandment the Law is fulfilled. Yet, Love is not a “feel good/wish well” sentiment that Christians to profess:
7Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. 8Whoever does not love does not know God, because God is love. (1 St. John 4:7-8)
But God did not merely state that He Loved us… He actually brought that “feeling” into physical fruition:
9This is how God showed his love among us: He sent his one and only Son into the world that we might live through him. 10This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. (1 St. John 4:9-10)
This is the “works” that must accompany “Faith” in order to demonstrated that we abide in Christ and are working out our Salvation:
11Dear friends, since God so loved us, we also ought to love one another. 12No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us. 13We know that we live in him and he in us, because he has given us of his Spirit. 14And we have seen and testify that the Father has sent his Son to be the Savior of the world. 15If anyone acknowledges that Jesus is the Son of God, God lives in him and he in God. 16And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in him. (1 St. John 4:11-16)
Jesus equates Love with Obedience to Him and He states that Love must be active and physically demonstrated:
31"When the Son of Man comes in his glory, and all the angels with him, he will sit on his throne in heavenly glory. 32All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. 33He will put the sheep on his right and the goats on his left.
34"Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’
37"Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38When did we see you a stranger and invite you in, or needing clothes and clothe you? 39When did we see you sick or in prison and go to visit you?’
40"The King will reply, ‘I tell you the truth, whatever you did for one of the least of these brothers of mine, you did for me.’
41"Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’
44"They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’
45"He will reply, ‘I tell you the truth, whatever you did not do for one of the least of these, you did not do for me.’
46"Then they will go away to eternal punishment, but the righteous to eternal life." (St. Matthew 25:31-46)
St. Paul, understanding this very relationship between Salvation, Faith, and Love, warns that:
1If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. 2If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. 3If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing. (1 Corinthians 13:1-3)
Finally, Jesus gives us the deepest definition of Love:
John 15:13
Greater love has no one than this, that he lay down his life for his friends.
Faith alone is empty!
Maran atha!
