Necessary

Romans 1:17
For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last, just as it is written: "The righteous will live by faith."

Romans 3:22-25
This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference, for all have sinned and fall short of the glory of God, and are justified freely by his grace through the redemption that came by Christ Jesus. God presented him as a sacrifice of atonement, through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished—

Romans 3:28
For we maintain that a man is justified by faith apart from observing the law.

Romans 4:5
However, to the man who does not work but trusts God who justifies the wicked, his faith is credited as righteousness.

Romans 4:20-22
Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, being fully persuaded that God had power to do what he had promised. This is why "it was credited to him as righteousness."

Romans 5:1
Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ,

Romans 10:9-13
That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. As the Scripture says, "Anyone who trusts in him will never be put to shame." For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, for, "Everyone who calls on the name of the Lord will be saved."

Galatians 3:11
Clearly no one is justified before God by the law, because, "The righteous will live by faith."

Ephesians 2:8-9
For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— not by works, so that no one can boast.

John 1:12
Yet to all who received him, to those who believed in his name, he gave the right to become children of God—

John 3:15
that everyone who believes in him may have eternal life.

John 3:18
Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.

Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God's wrath remains on him."

John 5:24
"I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life.

John 8:24
I told you that you would die in your sins; if you do not believe that I am the one I claim to be, you will indeed die in your sins."

Jesus said to her, "I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die. Do you believe this?"

He then brought them out and asked, "Sirs, what must I do to be saved?" They replied, "Believe in the Lord Jesus, and you will be saved—you and your household."

2 Corinthians 13:5
Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the test?

Mark 16:16
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.

1 John 2:20
But you have an anointing from the Holy One, and all of you know the truth. I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. Who is the liar? It is the man who denies that Jesus is the Christ. Such a man is the antichrist—he denies the Father and the Son. No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.

1 John 3:23-23
And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. Those who obey his commands live in him, and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.

1 John 4:13-15
We know that we live in him and he in us, because he has given us of his Spirit. And we have seen and testify that the Father has sent his Son to be the Savior of the world. If anyone acknowledges that Jesus is the Son of God, God lives in him and he in God.

1 John 5:1
Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well.

1 John 5:5
Who is it that overcomes the world? Only he who believes that Jesus is the Son of God.

1 John 5:10-12
Anyone who believes in the Son of God has this testimony in his heart. Anyone who does not believe God has made him out to be a liar, because he has not believed the testimony God has given about his Son. And this is the testimony: God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son of God does not have life.

1 John 5:20
We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true—even in his Son Jesus Christ. He is the true God and eternal life.
