Unless -Revelation 2:22

Revelation 2:22 NIV
So I will cast her on a bed of suffering, and I will make those who commit adultery with her suffer intensely, unless they repent of her ways.

There is a consequence for intercourse with the world. It is a bed that seems pleasant at first, but it will end badly. There is no hope for the hopeless sinner. Our only hope lies in our faith in Jesus. His love has provided the "unless" in this verse. His grace allows a return home. It is a turning back to God. The door to life is open. You don't even need to knock.

Revelation 17:1-2
1 One of the seven angels who had the seven bowls came and said to me, “Come, I will show you the punishment of the great prostitute, who sits by many waters. 2 With her the kings of the earth committed adultery, and the inhabitants of the earth were intoxicated with the wine of her adulteries.”

Revelation 18:3
For all the nations have drunk
the maddening wine of her adulteries.
The kings of the earth committed adultery with her,
and the merchants of the earth grew rich from her excessive luxuries.”

Ezekiel 23:28-30
“For this is what the Sovereign Lord says: I am about to deliver you into the hands of those you hate, to those you turned away from in disgust. 29 They will deal with you in hatred and take away everything you have worked for. They will leave you stark naked, and the shame of your prostitution will be exposed. Your lewdness and promiscuity 30 have brought this on you, because you lusted after the nations and defiled yourself with their idols.

Ezekiel 23:45
But righteous judges will sentence them to the punishment of women who commit adultery and shed blood, because they are adulterous and blood is on their hands.

Jeremiah 36:3
Perhaps when the people of Judah hear about every disaster I plan to inflict on them, they will each turn from their wicked ways; then I will forgive their wickedness and their sin.”

Ezekiel 33:11-12
Say to them, ‘As surely as I live, declares the Sovereign Lord, I take no pleasure in the death of the wicked, but rather that they turn from their ways and live. Turn! Turn from your evil ways! Why will you die, people of Israel? ’
12 “Therefore, son of man, say to your people, ‘If someone who is righteous disobeys, that person’s former righteousness will count for nothing. And if someone who is wicked repents, that person’s former wickedness will not bring condemnation. The righteous person who sins will not be allowed to live even though they were formerly righteous. ’

I tell you, no! But unless you repent, you too will all perish.

2 Timothy 2:25-26
Opponents must be gently instructed, in the hope that God will grant them repentance leading them to a knowledge of the truth, 26 and that they will come to their senses and escape from the trap of the devil, who has taken them captive to do his will.
