Hello Know1,
Which bible you reading? Mine says that repentance is required, otherwise the unrepentant will perish:
At that time, some of those present told Jesus about the Galileans whose blood Pilate had mixed with their sacrifices. To this He replied, “Do you think that these Galileans were worse sinners than all the other Galileans, because they suffered this fate? No, I tell you. But unless you repent, you too will all perish. Or those eighteen who were killed when the tower of Siloam collapsed on them: Do you think that they were more sinful than all the others living in Jerusalem? No, I tell you. But unless you repent, you too will all perish.” - Luke 13:1-5
Watch yourselves. If your brother sins, rebuke him; and if he repents, forgive him. Even if he sins against you seven times in a day, and seven times returns to say, ‘I repent,’ you must forgive him.” – Luke 17:3-4
When the people heard this, they were cut to the heart and asked Peter and the other apostles, “Brothers, what shall we do?” Peter replied, “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.
And now, brothers, I know that you acted in ignorance, as did your leaders. 18But in this way God has fulfilled what He foretold through all the prophets, saying that His Christ would suffer. Repent, then, and turn back, so that your sins may be wiped away, 20that times of refreshing may come from the presence of the Lord, and that He may send Jesus, the Christ, who has been appointed for you. – Acts 3:17-22
Beloved, do not let this one thing escape your notice: With the Lord a day is like a thousand years, and a thousand years are like a day. 9The Lord is not slow to fulfill His promise as some understand slowness, but is patient with you, not wanting anyone to perish, but everyone to come to repentance. – 2 Pet.3:8-9
But I have this against you: You have abandoned your first love. Therefore, keep in mind how far you have fallen. Repent and perform the deeds you did at first. But if you do not repent, I will come to you and remove your lampstand from its place. – Rev.2:4-5
But I have a few things against you, because some of you hold to the teaching of Balaam, who taught Balak to place a stumbling block before the Israelites so they would eat food sacrificed to idols and commit sexual immorality. In the same way, some of you also hold to the teaching of the Nicolaitans. Therefore repent! Otherwise I will come to you shortly and wage war against them with the sword of My mouth. – Rev.2:14-16
But I have this against you: You tolerate that woman Jezebel, who calls herself a prophetess. By her teaching she misleads My servants to be sexually immoral and to eat food sacrificed to idols. Even though I have given her time to repent of her immorality, she is unwilling. Behold, I will cast her onto a bed of sickness, and those who commit adultery with her will suffer great tribulation unless they repent of her deeds. Then I will strike her children dead, and all the churches will know that I am the One who searches minds and hearts, and I will repay each of you according to your deeds. – Rev.2:20-23
I know your deeds; you have a reputation for being alive, yet you are dead. 2Wake up and strengthen what remains, which was about to die; for I have found your deeds incomplete in the sight of My God. Remember, then, what you have received and heard. Keep it and repent. If you do not wake up, I will come like a thief, and you will not know the hour when I will come upon you. – Rev.3:1-3
You say, ‘I am rich; I have grown wealthy and need nothing.’ But you do not realize that you are wretched, pitiful, poor, blind, and naked. I counsel you to buy from Me gold refined by fire so that you may become rich, white garments so that you may be clothed and your shameful nakedness not exposed, and salve to anoint your eyes so that you may see. Those I love, I rebuke and discipline. Therefore be earnest and repent. – Rev.3:19
Anyone who does not repent is willfully living according to the sinful nature, which leads to death.
