What makes this good news is the bad news about you:
For all have sinned and fall short of the glory of God. - Romans 3:23
Sin means breaking the law. In this case God's law. This is bad news because perfection is required by God. Lawbreakers must pay the just penalty for breaking the law. That penalty is the lake of fire (the second death).
All liars, their part will be in the lake that burns with fire and brimstone, which is the second death. - Revelation 21:8
Have you ever told a lie? Have you ever taken something that does not belong to you, no matter how small? Have you ever looked at another person with lust? In Matthew 5 Jesus said:
You have heard that it was said, ‘You shall not commit adultery’; but I say to you that everyone who looks at a woman with lust for her has already committed adultery with her in his heart.'
You have broken God's laws. You have sinned. There must be justice, and that means eternity in hell, the lake of fire, the second death. Unless...
Unless there was someone willing to pay that penalty on your behalf. Someone who will take on themselves the consequences you deserve. And there is. There is one person who can and will do that. That person is Jesus Christ. If you trust this is true, and repent (turn away from disobeying God), Jesus' death is applied to your account and you are freed from the penalty of sin to be with God forever.
