Christendom has had all kinds of variety of beliefs, heretics of all shades, and disagreements on a multitude of issues.
Saying that everyone is saved is Here is the ballpark & my view:
1 Peter 1
Blessed
be the God and Father of our Lord Jesus Christ, who according to his great mercy begat us again unto a living hope by the resurrection of Jesus Christ from the dead, to
an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you, who by the power of God are guarded through
faith unto a salvation ready to be revealed in the last time.
John 3:16
“For God so loved the world, that he gave his only Son, that whoever
believes in him should not perish but
have eternal life.

believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
1 John 5:13
I write these things to you who
believe in the name of the Son of God that you may know that you have eternal life.
1 John 5:10-13
Whoever
believes in the Son of God has the testimony in himself. Whoever does not
believe God has made him a liar, because he has not
believed in the testimony that God has borne concerning his Son. And this is the testimony, that God gave us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life. I write these things to you who
believe in the name of the Son of God that you may know that you have eternal life.
Ephesians 1:13
In him you also, when you heard the word of truth, the gospel of your salvation, and
believed in him, were sealed with the promised Holy Spirit,

believes on him, should have eternal life; and I will raise him up at the last day.

faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one

Truly, truly, I say to you, whoever
believes has eternal life.
John 3:36
Whoever
believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.
John 3:18
Whoever
believes in him is not condemned, but whoever does not
believe is condemned already, because he has not
believed in the name of the only Son of God.
joy,
1 Peter 1:3-5
Blessed
be the God and Father of our Lord Jesus Christ, who according to his great mercy begat us again unto a living hope by the resurrection of Jesus Christ from the dead,
4 unto an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
5 who by the power of God are guarded through
faith unto a salvation ready to be revealed in the last time.
John 1:12
But to all who did receive him, who
believed in his name, he gave the right to become children of God,
Revelation 3:5
The one who overcomes will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father…
1 John 5:4-5 For whatsoever is begotten of God overcometh the world: and this is the victory that has overcome the world,
even our
faith. And who is he who overcomes the world, but he that
believes that Jesus is the Son of God? For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our
faith.
JOHN 20:30
Many other signs therefore did Jesus in the presence of the disciples, which are not written in this book:
31 but these are written, that ye may
believe that Jesus is the Christ, the Son of God; and that believing ye may have life in his name.
Act 13:48
And as the Gentiles heard this, they were glad, and glorified the word of God: and as many as were ordained to eternal life
believed.
Faithful is the saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief:
16 howbeit for this cause I obtained mercy, that in me as chief might Jesus Christ show forth all his longsuffering, for an ensample of them that should thereafter
believe on him unto eternal life.
1 Tim 1:15-17
Faithful is the saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief: howbeit for this cause I obtained mercy, that in me as chief might Jesus Christ show forth all his longsuffering, for an ensample of them that should thereafter
believe on him unto eternal life.
1 John 5:13
These things have I written unto you, that ye may know that ye have eternal life,
even unto you that
believe on the name of the Son of God.
Eph 1:10ff
to sum up all things in Christ, the things in the heavens, and the things upon the earth; in him,
I say in whom also we were made a heritage, having been foreordained according to the purpose of him who worketh all things after the counsel of his will;
12 to the end that we should be unto the praise of his glory, we who had before hoped in Christ:
13 in whom ye also, having heard the word of the truth, the gospel of your salvation,— in whom, having also
believed, ye were sealed with the Holy Spirit of promise,
14 which is an earnest of our inheritance, unto the redemption of
God’s own possession, unto the praise of his glory.
Luke 8:11-12
Now the parable is this: The seed is the word of God.
12 And those by the way side are they that have heard; then cometh the devil, and taketh away the word from their heart, that they may not
believe and be saved.
Acts 16:31
And they said,
Believe on the Lord Jesus, and thou shalt be saved, thou and thy house.
1 Cor 1:21
it was God’s good pleasure through the foolishness of the preaching to save them that
believe.
Gal 2:15-16
We being Jews by nature, and not sinners of the Gentiles,
16 yet knowing that a man is not justified by the works of the law but through
faith in Jesus Christ, even we
believed on Christ Jesus, that we might be justified by
faith in Christ, and not by the works of the law: because by the works of the law shall no flesh shall be justified.
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up; that whosoever
believes may in him have eternal life.
John 3:14-18
For God so loved the world, that he gave his only Son, that whosoever
believes on him should not perish, but have eternal life.
1For God sent not the Son into the world to judge the world; but that the world should be saved through him.
1He that
believes on him is not judged: he that
believes not hath been judged already, because he hath not
believed on the name of the only Son of God.
John 5:24
2Verily, verily, I say unto you, He that heareth my word, and
believes him that sent me, hath eternal life, and cometh not into judgment, but hath passed out of death into life.

Verily, verily, I say unto you, He that
believes hath eternal life.
John 10:27
But ye
believe not, because ye are not of my sheep. My sheep hear my voice, and I know them, and they follow me: and I give unto them eternal life; and they shall never perish, and no one shall snatch them out of my hand. My Father, who hath given
them unto me, is greater than all; and no one is able to snatch
them out of the Father’s hand.
1 John 5:10-12
He that
believes on the Son of God hath the witness in him: he that
believes not God hath made him a liar; because he hath not
believed in the witness that God hath borne concerning his Son. And the witness is this, that God gave unto us eternal life, and this life is in his Son.
12 He that hath the Son hath the life; he that hath not the Son of God hath not the life.
Ps 37:5-6
Commit thy way unto Jehovah;
Trust also in him, and he will bring it to pass.
And he will make thy righteousness to go forth as the light,
And thy justice as the noonday.
Acts 15:8
And God, who knoweth the heart, bare them witness, giving them the Holy Spirit, even as he did unto us; and he made no distinction between us and them, cleansing their hearts by
faith.
Acts 26:18b
that they may receive remission of sins and an inheritance among them that are sanctified by
faith in me.
Rom 1:16-17
For I am not ashamed of the gospel: for it is the power of God unto salvation to every one that
believes; to the Jew first, and also to the Greek.
17 For therein is revealed a righteousness of God from
faith unto
faith: as it is written, But the righteous shall live by
faith.
Rom 3:21-30
But now apart from the law a righteousness of God hath been manifested, being witnessed by the law and the prophets;
22 even the righteousness of God through
faith in Jesus Christ unto all them that
believe; for there is no distinction;
23 for all have sinned, and fall short of the glory of God;
24 being justified freely by his grace through the redemption that is in Christ Jesus:
25 whom God set forth
to be a propitiation, through
faith, in his blood, to show his righteousness because of the passing over of the sins done aforetime, in the forbearance of God;
26 for the showing,
I say, of his righteousness at this present season: that he might himself be just, and the justifier of him that hath
faith in Jesus.
27 Where then is the glorying? It is excluded. By what manner of law? of works? Nay: but by a law of
faith.
28 We reckon therefore that a man is justified by
faith apart from the works of the law.
29 Or is God
the God of Jews only? is he not
the God of Gentiles also? Yea, of Gentiles also:
30 if so be that God is one, and he shall justify the circumcision by
faith, and the uncircumcision through
faith.
Rom 4:1ff
:1 What then shall we say that Abraham, our forefather, hath found according to the flesh?
2 For if Abraham was justified by works, he hath whereof to glory; but not toward God.
3 For what saith the scripture? And Abraham
believed God, and it was reckoned unto him for righteousness.
4 Now to him that worketh, the reward is not reckoned as of grace, but as of debt.
5 But to him that worketh not, but
believes on him that justifieth the ungodly, his
faith is reckoned for righteousness.
6 Even as David also pronounceth blessing upon the man, unto whom God reckoneth righteousness apart from works,
7 saying,
Blessed are they whose iniquities are forgiven,
And whose sins are covered.
8 Blessed is the man to whom the Lord will not reckon sin.
9 Is this blessing then pronounced upon the circumcision, or upon the uncircumcision also? for we say, To Abraham his
faith was reckoned for righteousness.
10 How then was it reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision:
11 and he received the sign of circumcision, a seal of the righteousness of the
faith which he had while he was in uncircumcision: that he might be the father of all them that
believe, though they be in uncircumcision, that righteousness might be reckoned unto them;
12 and the father of circumcision to them who not only are of the circumcision, but who also walk in the steps of that
faith of our father Abraham which he had in uncircumcision.
13 For not through the law was the promise to Abraham or to his seed that he should be heir of the world, but through the righteousness of
faith.
14 For if they that are of the law are heirs,
faith is made void, and the promise is made of none effect:
15 for the law worketh wrath; but where there is no law, neither is there transgression.
16 For this cause
it is of
faith, that
it may be according to grace; to the end that the promise may be sure to all the seed; not to that only which is of the law, but to that also which is of the
faith of Abraham, who is the father of us all
17 (as it is written, A father of many nations have I made thee) before him whom he
believed,
even God, who giveth life to the dead, and calleth the things that are not, as though they were.
18 Who in hope
believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, So shall thy seed be.
19 And without being weakened in
faith he considered his own body now as good as dead (he being about a hundred years old), and the deadness of Sarah’s womb;
20 yet, looking unto the promise of God, he wavered not through unbelief, but waxed strong through
faith, giving glory to God,
21 and being fully assured that what he had promised, he was able also to perform.
22 Wherefore also it was reckoned unto him for righteousness.
Rom 5:1-2
Being therefore justified by
faith, let us have peace with God through our Lord Jesus Christ; through whom also we have had our access by
faith into this grace wherein we stand; and let us boast in hope of the glory of God.
Rom 9:30:
What shall we say then? That the Gentiles, who followed not after righteousness, attained to righteousness, even the righteousness which is of
faith: but Israel, following after a law of righteousness, did not arrive at
that law. Wherefore? Because
they sought it not by
faith, but as it were by works. They stumbled at the stone of stumbling; even as it is written,
Behold, I lay in Zion a stone of stumbling and a rock of offence:
And he that
believes on him shall not be put to shame.
Rom 10:4ff
For Christ is the end of the law unto righteousness to every one that
believes. For Moses writeth that the man that doeth the righteousness which is of the law shall live thereby. But the righteousness which is of
faith saith thus, Say not in thy heart, Who shall ascend into heaven? (that is, to bring Christ down
or, Who shall descend into the abyss? (that is, to bring Christ up from the dead.) But what saith it? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of
faith, which we preach.
