There are errors in your post and indications, and I will show you:
1. Firstly, tell me, do you sin? YES OR NO? IF yes, then are your sinning accidentally or willful from free will or something else, is something tampering with your free will to choose what you want to do? So why are you sinning exactly?
2. Can a person only be saved or remain saved through their continuous repentance? IN other words, are we saved and do we remain saved by REPENTING WORKS or by continuous FAITH IN JESUS?
3. Have you perfectly repented of all your sins? Yes or No? If no, do you believe you are saved or lost today?
4. 1 John 1:9 is the only verse in the entire new testament that speaks about confession of sins, and it doesn't apply to believers, it's a message to unbelievers who refused to admit and acknowledge they were sinners to begin with.
In a nutshell this verse is not talking to or about the Christian’s need to confess sins in order to be forgiven! John is talking about boastful false teachers who believed that they had never ever sinned!
John angers back at them and says that if these false teachers hoped to be saved then they needed to confess [acknowledge and admit] that they were sinners. In other words, 1 John 1:9 is referring to the point in time that a person comes to Jesus for the first time. When they come to Christ they need to first “confess” their sinfulness. These false teachers were saying that they had no sin – see 1 John 1:8. John said that they were liars and deceiving themselves – the truth was not in them – they in fact were not yet saved. Read 1 John right through and this point becomes clear. This is the only verse in the New Testament that links confession of sin with forgiveness and it is not even talking about or to believers!
If you believe that you need to badger God with your confession and repentance in order for him to provide you with forgiveness then you really do not believe that God established your forgiveness through the blood 2000 years ago.
"...Who has bewitched you? Before your very eyes Jesus Christ was clearly portrayed as crucified. I would like to learn just one thing from you: Did you receive the Spirit by observing the law, or by believing what you heard? Are you so foolish? After beginning with the Spirit, are you now trying to attain your goal by human effort?" - Galatians 3:1-3
You certainly must be posting in the wrong topic... I'm talking about knowing that your sinning, and you don't care because "Grace" has got your back...
Romans 6:15 What then? Shall we sin, because we are not under the law, but under grace? God forbid.
God does not want us to sin. Jesus does not want us to sin.
Jesus himself even said, John 5:14 Afterward Jesus findeth him in the temple, and said unto him,
Behold, thou art made whole: sin no more, lest a worse thing come unto thee.
And again, Jesus says, John 8:11 She said, No man, Lord. And Jesus said unto her,
Neither do I condemn thee: go, and sin no more.
If you want to willfully sin, go right ahead, but your going against what God wants of you and when something worse happens to you, you've got nobody to fault but your own stubbornness. With that, I'd say your also selfish with no regard for anyone other than yourself. When people willfully sin, it often effects others around them, and it can hurt other people around them. So if you don't care who you hurt, as long as you can get your fix of sin, then whatever, you've brought wrath upon yourself. Welcome to a taste of hell on earth.
It's almost ironic. My brother died a few months ago as a direct consequence of his lifestyle. He even told our Mom, "I'm either going to die, or end up in prison". Why? Because he didn't want to change the path he was going down... even when he knew the consequences.
So don't sit there and tell me that sinning is ok. It's not, and I'm not the only one that has a story. I'm sure you have your own as well.
Scripture clearly states,
Revelation 21:7-8 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death
You can talk grace till your blue in the face, but you'll have a hard time convincing me that somebody who willfully commits the above sins with the idea that on their death bed they've got a magic ace, and all they have to do is confess Jesus as their savior and bam, they've got a free ticket into heaven, then I say balderdash. That's not grace, that's extortion.
Let's look at Esau,
Hebrew 12
13And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
14Follow peace with all men, and holiness, without which no man shall see the Lord:
15Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;
16Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.
17For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
Do you see how Esau is placed in with the fornicators and profane? He searched for the blessing, even with tearful repentance and he did not receive the blessing, and is counted among them.
In Luke 12, we have the parable that speaks of a farmer who, in a time of famine has a bumper crop. But instead of sharing it, he builds bigger barns and stores it for himself. And what does God do? He takes that man's life. Why? Because God cares what you do!
There is also another parable in Luke 16 Where Lazarus gets sent to hell for his actions in the present world... and even in hell all he can think about is his own relatives, and not others...
Hell is a reality, both in this world and the world to come, and God cares about you in this world, and the world to come.
Again, we can talk grace all day long, and we can talk about being 'saved' all day long, but I think that God is more in the transformation business than he is in the "saving" business, because to be saved, is to be transformed.. and sometimes that takes awhile, but we can endure, and finish the race. And no, it's not about earning salvation, it's about living your life the way God created us to live, and by doing so, we can have life here, now.. today, more abundant. It's all about the way... and Jesus is that Way.
Can God transform the life of a fornicator, a murders or one that profanes? Absolutely! Scriptures even say that even the angels rejoice when this happens!
Genesis 3:4 And the serpent said unto the woman, Ye shall not surely die:
Let's not be deceived by the lie.
Want to feel bad? Just keep on sinning...
Genesis 4:6 And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?
Want to feel better?
Genesis 4:7 If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
Have you ever wondered why Jesus said, "Do you want to be made well?" to the same man he said, "
sin no more, lest a worse thing come unto thee." (John 5)
There are other verses that speak to the nature and importance of confessing one's sin. However, confession and repentance are closely related. Can you do one without the other? While I agree that our salvation does not hinge on constant repentance/confession, there is an on going element in our relationship with Christ through this continued act, and we should give it some weight. It's a very necessary element growth in Christ as Christians. If we are calling ourselves saved sinners, wouldn't we want to also flee from sin in our lives as best we can? And does that not require an element of conscious effort on our part, where we have to admit from time to time that we are wrong on our ways, thinking, feelings that can be labeled as sin in the eyes of God? 
(These crazy lawyers and there letter phone numbers) 
And it seems you have accepted and trust in Jesus to be your 100% complete and one and only sole Savior and you do not trust in yourself to be your own Savior.
grace has your back how? If you mean salvation then I have to say yes. Grace has your back. If you have accepted Christ as your savior, but if you mean your relationship with Christ, then grace is not what really glues that together. Especially from God's point of view.
