What happens to people who never heard of Jesus?

Romans 1:18–2:16

¹⁸For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; ¹⁹Because that which may be known of God is manifest in them; for God hath shewed it unto them. ²⁰For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: ²¹Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. ²²Professing themselves to be wise, they became fools, ²³And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things. ²⁴Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: ²⁵Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen. ²⁶For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: ²⁷And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet. ²⁸And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; ²⁹Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, ³⁰Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, ³¹Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: ³²Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them. ¹Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things. ²But we are sure that the judgment of God is according to truth against them which commit such things. ³And thinkest thou this, O man, that judgest them which do such things, and doest the same, that thou shalt escape the judgment of God? ⁴Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance? ⁵But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God; ⁶Who will render to every man according to his deeds: ⁷To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life: ⁸But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath, ⁹Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile; ¹⁰But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile: ¹¹For there is no respect of persons with God. ¹²For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law; ¹³(For not the hearers of the law are just before God, but the doers of the law shall be justified. ¹⁴For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: ¹⁵Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;) ¹⁶In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.

Acts 17:22–31

²²Then Paul stood in the midst of Mars’ hill, and said, Ye men of Athens, I perceive that in all things ye are too superstitious. ²³For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you. ²⁴God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands; ²⁵Neither is worshipped with men’s hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things; ²⁶And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; ²⁷That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us: ²⁸For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. ²⁹Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device. ³⁰And the times of this ignorance God winked at; but now commandeth all men every where to repent: ³¹Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.

Acts 10:34–48

³⁴Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons: ³⁵But in every nation he that feareth him, and worketh righteousness, is accepted with him. ³⁶The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:) ³⁷That word, I say, ye know, which was published throughout all Judæa, and began from Galilee, after the baptism which John preached; ³⁸How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him. ³⁹And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: ⁴⁰Him God raised up the third day, and shewed him openly; ⁴¹Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. ⁴²And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead. ⁴³To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins. ⁴⁴While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. ⁴⁵And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. ⁴⁶For they heard them speak with tongues, and magnify God. Then answered Peter, ⁴⁷Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? ⁴⁸And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.

Genesis 18:22–33

²²And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD. ²³And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked? ²⁴Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein? ²⁵That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee: Shall not the Judge of all the earth do right? ²⁶And the LORD said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes. ²⁷And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which am but dust and ashes: ²⁸Peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, If I find there forty and five, I will not destroy it. ²⁹And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for forty’s sake. ³⁰And he said unto him, Oh let not the Lord be angry, and I will speak: Peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there. ³¹And he said, Behold now, I have taken upon me to speak unto the Lord: Peradventure there shall be twenty found there. And he said, I will not destroy it for twenty’s sake. ³²And he said, Oh let not the Lord be angry, and I will speak yet but this once: Peradventure ten shall be found there. And he said, I will not destroy it for ten’s sake. ³³And the LORD went his way, as soon as he had left communing with Abraham: and Abraham returned unto his place.
