What do I have to believe? What is not enough, and what is too much? What is the irreducible, minimum that must be believed for me to be saved?

Christ's conversation with Nicodemus in John chapter three, verses three through eight. Jesus answered and said to him, "Truly, truly, I say to you, unless one is born again, he cannot see the kingdom of God." Nicodemus *said to Him, "How can a man be born when he is old? He cannot enter a second time into his mother's womb and be born, can he?" Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, 'You must be born again.' The wind blows where it wishes and you hear the sound of it, but do not know where it comes from and where it is going; so is everyone who is born of the Spirit."

Believing Romans chapter eight, verses one through eleven. There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life in Christ Jesus has set you free from the law of sin and of death. For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh, in order that the requirement of the Law might be fulfilled in us, who do not walk according to the flesh, but according to the Spirit. For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit. For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so; and those who are in the flesh cannot please God. However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him. And if Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who indwells you.

You can also read Romans chapter ten, verses eight through thirteen. But what does it say? "THE WORD IS NEAR YOU, IN YOUR MOUTH AND IN YOUR HEART"-that is, the word of faith which we are preaching, that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you shall be saved; for with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. For the Scripture says, "WHOEVER BELIEVES IN HIM WILL NOT BE DISAPPOINTED." For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call upon Him; for "WHOEVER WILL CALL UPON THE NAME OF THE LORD WILL BE SAVED."

And finally Ephesians chapter one, verses eight through nine help us understand salvation. For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, that no one should boast.

Scripture has all the answers to good questions.

Don't be bewitched, but stick to the Scripture.
