Let me now annotate the OP with scriptures given by you good people:
*
1. We are free to believe or disbelieve according to our own free will.
Joshua 24:15 But if serving the LORD seems undesirable to you, then choose for yourselves this day whom you will serve
[Deu 30:15 NKJV] "See, I have set before you today life and good, death and evil,
[Deu 30:19 NKJV] "I call heaven and earth as witnesses today against you, [that] I have set before you life and death, blessing and cursing; therefore choose life, that both you and your descendants may live;
John 6:
27 Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.
28Then said they unto him, What shall we do, that we might work the works of God?
29Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
Romans 6:16 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?
*
2. Righteousness/Salvation is based upon belief/faith.
3. Belief and faith are not acts of works.
4. We are not saved by acts of works.
Romans 4:
1 What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter?
2If, in fact, Abraham was justified by works, he had something to boast about—but not before God.
3 What does Scripture say? “Abraham believed God, and it was credited to him as righteousness. [SUP]“[/SUP]
4Now to the one who works, wages are not credited as a gift but as an obligation.
5However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness.
6David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works
13It was not through the law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith.
14For if those who depend on the law are heirs, faith means nothing and the promise is worthless,
15because the law brings wrath. And where there is no law there is no transgression.
16Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law but also to those who have the faith of Abraham. He is the father of us all.
17As it is written: “I have made you a father of many nations.” He is our father in the sight of God, in whom he believed—the God who gives life to the dead and calls into being things that were not.
18Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, “So shall your offspring be.”[SUP]

19Without weakening in his faith, he faced the fact that his body was as good as dead—since he was about a hundred years old—and that Sarah’s womb was also dead.
20Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God,
21being fully persuaded that God had power to do what he had promised.
22This is why “it was credited to him as righteousness.”
23The words “it was credited to him” were written not for him alone,
24but also for us, to whom God will credit righteousness—for us who believe in him who raised Jesus our Lord from the dead.
Eph 2:8-9 For by grace are you saved through faith, and that not of yourselves. It’s a gift of God and not of works, let any man should boast.
Acts 16:
31 They replied, “Believe in the Lord Jesus, and you will be saved”
"Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ." Romans 5:1
John 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
Romans 11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.

5. Works are a reliable discerner of salvation
James 2:
14What good is it, my brothers and sisters, if someone claims to have faith but has no deeds? Can such faith save them?
15Suppose a brother or a sister is without clothes and daily food.
16If one of you says to them, “Go in peace; keep warm and well fed,” but does nothing about their physical needs, what good is it?
17In the same way, faith by itself, if it is not accompanied by action, is dead.
18But someone will say, “You have faith; I have deeds.” Show me your faith without deeds, and I will show you my faith by my deeds.
19You believe that there is one God. Good! Even the demons believe that—and shudder.
20You foolish person, do you want evidence that faith without deeds is useless[SUP]
d[/SUP] ?
21Was not our father Abraham considered righteous for what he did when he offered his son Isaac on the altar?
22You see that his faith and his actions were working together, and his faith was made complete by what he did.
23And the scripture was fulfilled that says, “Abraham believed God, and it was credited to him as righteousness,”[SUP]
e[/SUP] and he was called God’s friend.
24You see that a person is considered righteous by what they do and not by faith alone.
25In the same way, was not even Rahab the prostitute considered righteous for what she did when she gave lodging to the spies and sent them off in a different direction?
26As the body without the spirit is dead, so faith without deeds is dead.
