Thanks for writing. 1 John 1.8-10 tackles your question pretty directly, so I'll talk about that.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
1 John was written to believers. Sinning is not something that Christians ever totally escape from, and if someone claims that they have, John is pretty explicit in saying they're not telling the truth. Even though our sin nature has been redeemed, it's still in us raising its ugly head (Rom. 7.7-25). Even though the power of sin in us is changed, it's not gone.
But it's not the sin in us that is the condition of whether we are saved or not. We are saved when Jesus changes our nature from the nature of sin to his nature. And even though the Holy Spirit is working in us to change our thoughts, attitudes, and behaviors, it's a rather lengthy process. When a person gets saved, Jesus instantly changes their nature from that of sin to that of Jesus and that person is a new creation—born again. And that's when the process begins of what is called sanctification: the gradual changes of thoughts, attitudes, values, and behavior so that they become conformed to that of Jesus. So that's how we can be saved if we knowingly sin against God (even daily) and rebel against his commands.
That's why the Bible is insistent that salvation isn't by "works". A person is saved if they have the nature of Jesus rather than the nature of sin, not on the basis of our behavior or our "daily sin". I mean, one we have the nature of Jesus, we are from that point under the "law of grace". It's the great thing about grace: it's a gift, and doesn't depend on my earning it. That's actually the whole point: we're all sinners, but a way has been made for us to have a relationship with God anyway.
Now, I should also clarify that this doesn't mean that I'm OK to sin knowingly and willingly. I have a part to play in this, too. You know, if I really do love God, I'm going to do my best to live in a way that reflects that love, and not knowingly do things that are sin and rebellion. If I'm sinning on purpose, just rubbing it in his face like, "Hey, you'll forgive me so who cares?", that's a problem (Rom. 6.1-2). But if I'm trying to show my love, as I do with my wife, but if I flub up, as I do with my wife, then grace forgives my foibles and failures (Rom. 5.8; 1 Pet. 4.8).
You asked why the Bible says that we should stop the one sin we know we do if it's impossible for us to stop it. The Bible says that stopping sin isn't just a matter of will-power, but the power of the Holy Spirit in us, working with us to stop it. We don't have the power within ourselves, but with God's power in us, that's where the possibility exists.
I may not have answered all of your questions, so feel free to dialogue about this stuff, ask for clarification, or ask more.
