Answer
Paul, a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God, which he promised beforehand through his prophets in the holy Scriptures, concerning his Son, who was descended from David according to the flesh and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations, including you who are called to belong to Jesus Christ. (Romans 1:1–6, ESV)
• the message he preached is the gospel of God (verse 1)
• the good news Paul preached, the gospel of God, was foretold by the holy prophets long before Paul lived (verse 2)
• the gospel message focuses on Christ Jesus, a descendant of King David according to the Scriptures (verse 3)
• though born of a woman and, thus, being fully man, Jesus was also fully God and divine in nature; His Sonship was indisputably established by the Holy Spirit through His bodily resurrection (verse 4)
• Paul’s authority as an apostle, being called to preach the gospel of God, was granted to him by none other than the Lord Jesus Christ (verse 5)
• those called of God, having heard and believed the gospel of God, now belong to the Lord Jesus (verse 6)
Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain. For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Cephas, and then to the Twelve. After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born. (1 Corinthians 15:1–4, ESV)
• there is only one gospel: it is the gospel of God that Paul preached and in which the redeemed have taken their stand (verse 1)
• this is the gospel that saves, the gospel Paul delivered, and the gospel that must never be forgotten or discarded (verse 2)
• according to the Scriptures, the Lord Jesus died for our sins. His sacrifice paid our sin debt (verse 3)
• after His lifeless body was taken from the cross and laid to rest in a borrowed tomb, Jesus miraculously walked away from where He lay, as foretold by the holy prophets, proving His absolute power over sin and death (verse 4)
And if you call on him as Father who judges impartially according to each one's deeds, conduct yourselves with fear throughout the time of your exile, knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot. He was foreknown before the foundation of the world but was made manifest in the last times for the sake of you. (1 Peter 1:17–20, ESV, emphasis added)
The Lord God said to the serpent,
“Because you have done this,
cursed are you above all livestock
and above all beasts of the field;
on your belly you shall go,
and dust you shall eat
all the days of your life.
I will put enmity between you and the woman,
and between your offspring and her offspring;
he shall bruise your head,
and you shall bruise his heel.” (Genesis 3:14–15, ESV, emphasis added)
The Jews answered him, “Are we not right in saying that you are a Samaritan and have a demon?” Jesus answered, “I do not have a demon, but I honor my Father, and you dishonor me. Yet I do not seek my own glory; there is One who seeks it, and he is the judge. Truly, truly, I say to you, if anyone keeps my word, he will never see death.” The Jews said to him, “Now we know that you have a demon! Abraham died, as did the prophets, yet you say, ‘If anyone keeps my word, he will never taste death.’ Are you greater than our father Abraham, who died? And the prophets died! Who do you make yourself out to be?” Jesus answered, “If I glorify myself, my glory is nothing. It is my Father who glorifies me, of whom you say, ‘He is our God.’ But you have not known him. I know him. If I were to say that I do not know him, I would be a liar like you, but I do know him and I keep his word. Your father Abraham rejoiced to see my day. He saw it and was glad.” (John 8:48–56, ESV, emphasis added).
Surely he has borne our griefs
and carried our sorrows;
yet we esteemed him stricken,
smitten by God, and afflicted.
But he was pierced for our transgressions;
he was crushed for our iniquities;
upon him was the chastisement that brought us peace,
and with his wounds we are healed.
All we like sheep have gone astray;
we have turned—every one—to his own way;
and the Lord has laid on him
the iniquity of us all. (Isaiah 53:4–6, ESV)
The next day [John] saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! This is he of whom I said, ‘After me comes a man who ranks before me, because he was before me.’” (John 1:29–30, ESV)
For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. 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. (John 3:16–18, ESV)
“Brothers, I may say to you with confidence about the patriarch David that he both died and was buried, and his tomb is with us to this day. Being therefore a prophet, and knowing that God had sworn with an oath to him that he would set one of his descendants on his throne, he foresaw and spoke about the resurrection of the Christ, that he was not abandoned to Hades, nor did his flesh see corruption. This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing. For David did not ascend into the heavens, but he himself says,
‘The Lord said to my Lord,
“Sit at my right hand,
until I make your enemies your footstool.”’
Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified.”
Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.” (Acts 2:29–38, ESV)
• Christ Jesus was a descendant of King David (verse 30)
• Christ Jesus was raised from the dead (verse 31)
• Peter and many others were eye-witnesses of our Lord’s bodily resurrection (verse 32)
• now that Jesus sits at the right hand of the Father, the Holy Spirit of God begins His ministry (verse 33)
• God the Father promises God the Son that His enemies will be defeated (verses 34–35)
• the One crucified is both Lord and Christ (verse 36)
I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel—not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. (Galatians 1:6–9, ESV)
• those who follow a different gospel have, in truth, deserted our Lord Jesus and have turned their backs on His loving grace (verse 6)
• there is only one gospel, and all others are worthless distortions of the truth (verse 7)
• those who preach counterfeit gospel messages are heretics worthy of damnation (verses 8–9)
I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of you agree, and that there be no divisions among you, but that you be united in the same mind and the same judgment. For it has been reported to me by Chloe's people that there is quarreling among you, my brothers. What I mean is that each one of you says, “I follow Paul,” or “I follow Apollos,” or “I follow Cephas,” or “I follow Christ.” Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul? I thank God that I baptized none of you except Crispus and Gaius, so that no one may say that you were baptized in my name. (I did baptize also the household of Stephanas. Beyond that, I do not know whether I baptized anyone else.) For Christ did not send me to baptize but to preach the gospel, and not with words of eloquent wisdom, lest the cross of Christ be emptied of its power. (1 Corinthians 1:10–17, ESV)
