The theological answer, as I learned it, is most clearly spelled out in James 2:14-26, often referenced through the phrase “faith without works is dead”. The short version is: faith in Jesus will save you, not good deeds. However, if you have faith in Jesus, then that faith will manifest itself through good deeds. If someone proclaims their faith but doesn’t act lovingly, then they don’t actually have faith and won’t be saved. So a Christian should be a good person not because being good will save them, but because being good is a result of genuine faith.

The “be a good person” and “you’ll be forgiven” are two separate ideas. Digging into it requires digging into a lot of different religions and their beliefs. Churches and people disagree on how those go together.

I don’t feel your request of “understanding the reasoning that Christians use” relates well to the question in your title. Much of religion now is repeating dogma rather than spiritual awareness and bettering yourself.

TLDR: He doesn’t forgive anyone who sins, he forgives those who repent. Repent not meaning “feeling sorry” as many seem to explain, but actually meaning “to turn away” which means changing fundamentally as a human being. From a bad person to a good person.

Someone who doesn’t change and act good most of the time isn’t repentant, so isn’t forgiven. So basically, you prove it with your actions and how you live your life, not with just words only. By this measurement, Republican “Christians” aren’t repentant and so aren’t forgiven.

Not a Christian anymore, but I used to be for a very long time. Sidebar: “You will know a tree by it’s fruit” AKA you’ll know what kind of person someone is by what they do. Anyone who’s even skimmed the bible (especially the new testament) would easily understand that most conservative “christians” aren’t Christian at all, but rather like the Pharisees (phony religious types) that Jesus constantly argued with and condemned.

Other note: Sikhs actually live the way Christian claim to. I could easily make a “hard to swallow pill” meme which said: “Sikhs are better Christians than actual Christians are.”

Raised Catholic. Don’t believe in hell. Lost my mom recently so i hope there’s a heaven. If there is i assume it would be accepting of all. I try not to do things that hurt people because i don’t like to see people hurt.

Imagine Jesus as a director of a company that accepts all sincere applicants. The director assumes responsibility for all the mistakes his employees make, but he doesn’t assume responsibility for people who only claim to be employees. People who purposely commit crimes get fired and applications by people who apply with the purpose of commiting crimes get rejected for not being sincere. (That’s not to say someone who once was fired can’t reapply if they’re actually sincere about it, but since God sees into people’s hearts and minds, you can’t trick him.)

IIRC the trick is to get your forgiveness after the last dick move, but before you die. If you mess up the timing, eternal damnation so it’s safer to be good.

You absolutely don’t have to. But when you’re a Christian, you love God with all your heart, all your mind, and all your soul; and you love your neighbor as yourself. The result is that you do good works by virtue of doing God’s will. Good works are a result of salvation.

Welp you don’t want to hear it but the best explanation is religion is a system to scam commoners of their devotion and money. If things start not making sense then you should stop believing in Santa Claus
