Get real, bb: people commit wrongful deeds in a moment of passion, not with a forethought, thinking of the consequences or else they wouldn't be doing it.
It is only after the fact that they realize what they have done, regret it, and asks for forgiveness. More often than not, it's too late to undo the damage they have done.
Does that mean they will never do it again? Hardly. But they are told that they are fallen, that their will is weak, that they are human and humans err, and that people fall again and again, and are forgiven if they repent every time: "And if he sin against thee seven times in the day, and seven times turn again to thee, saying, I repent; thou shalt forgive him." [Luke 17:4]
It's not as if God gives three-strikes-and-you-are-out warning; there is no limit how many times you can fail. There is a certain degree of "assurance" that even if they give in to their weakness repeatedly they still stand a chance, as long as they believe in Jesus.
Luther pretty much said that when he mentioned a thousand fornications a day, and the Catholics are told that if they go to their regular confession, do their penance and take their communion, they are absolved. How is any of this a deterrent when there is only one sin that cnanot be forgiven, against the Holy Spirit [Luke 12:10]?
I don't think anyone deliberately says "it doesn't matter, I know I am saved" as they commit wrongful acts. People simply commit wrongful deeds, blame it on weakness, the devil, economy, whatever, and then ask for forgiveness.
But if they know that their sins are part of their "fallen nature" and therefore expected to repeat, and if they are told that if they confess they will be forgiven [1 John 1:9], that does not do much for them to try harder to not fail again.
Oh, by thge way, you can also repent at your last breath and be "saved" regardless what you did. That is not something that will make people try harder but rather it makes it easier for them to give in to their moment of weakness.
It is only after the fact that they realize what they have done, regret it, and asks for forgiveness. More often than not, it's too late to undo the damage they have done.
Get real yourself and get some reading comprehension lessons, for more reasons than one.
Do you not understand what presumptuously sins means? Do you not understand how sinning as a deliberate premeditated act counting on obtaining forgiveness later differs from falling into sin because we are imperfect sinful beings?
What you are addressing is not what JCB asked. Do try to stay on topic.
BB, perhaps you would also like to weigh in here since you were addressed in this comment.
Only a fool would gamble his eternity on counting on having that chance at his last breath. Nobody knows when that will be and often as not, there is is not the time to think, *Oh, I'm dying. This is my last breath. Please for give me God.*, Nor would I consider someone with that attitude to be sincere. God will not be mocked.
That is no different than the presumptuous sin that JCB mentioned, sinning and then counting on forgiveness. Again, spitting in God's face and expecting mercy from Him because you said the right words. sounds more like what man-made religions espouse.
