I think that acknowledging regret and try to do better would grant me forgiveness..
But I've seen people on here say that you need to repent every time. Repent if you swear, repent if you lie, repent if you steal, etc.. That's why I posed the title question and started this thread.
If you continually sin without repenting, isn't it kind of like you can do what you want, with no fear of retribution from God?
