I grew up going to church but I’m not religious now and I never really understood this part.
Please, no answers along the lines of “aha, that’s why Christianity is a sham” or “religions aren’t logical”. I don’t want to debate whether it’s right or wrong, I just want to understand the logic and reasoning that Christians use to explain this.
You won’t be forgiven no matter what. If you carry on sinning, there is no more forgiveness. The only thing you can expect is to be thrown into outer darkness forever where you will be mourning and regretting your decision.
Put it this way: you drove drunk and killed someone. You’ve been given the death penalty by the judge. But a person called Jesus steps in and says “I’ll take his place. Let him go free”.
Would you ever drink drive again after someone died in your place to give you a second chance? Surely not! You would be sober, very grateful and even yet to help other people not make the same mistake.
It’s the same with sin. Jesus paid a HEAVY price to redeem you. Don’t spit in his face by carrying on with the same sins. Instead be grateful and find out how you should live instead.
Read the 10 commandments in Exodus 20. And also read the gospels (Matthew, Mark, Luke, John) to see how Jesus further explains and practices these.
The goal is to become holy like Jesus
Hope that helps.
Good ELI5 answer. The “push” to do good comes from the feeling of thankfulness that you don’t have to take a death penalty from a wrongdoing, someone else is taking it instead.
Another take: Imagine when a friend takes you for a dinner treat, you’d be thankful for them that they paid for your food (and the food is not necessarily free, someone actually paid for the food). You’d at least try to be nice to him, as a gesture of thankfulness, and you wouldn’t want hurt their feeling after they took you for a treat. Deliberately or not.
