I disagree to an extent. It says to confess your sin. note your position in Christ.
While i like the tenor of your points we do confess our sin. In other words we agree with God concerning our true nature as sinners. This opens the way for us to accept the Grace of God which is confessed as you have above.
The whole context of that passage is being able to agree with God that we are sinners and thus in need of forgiveness and cleansing.
notice the context:
1Jn 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
If we say we have no sin we are deceived and do not know the truth.
But if we do the opposite and agree with God that we are sinners:
1Jn 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
The next verse basically says the opposite agian, that if we do not agree with God that we are sinners then we accuse God of being a liar:
1Jn 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
So the point is to acknowledge that we are sinners. Then we are opened up for God to forgive and cleanse.
In other words, you are insinuating that God forgives us only when we confess our sins. what about the sins of omission? what about those that we cannot remember? When you say “agreeing with God that we are sinners”, you are actually saying that Jesus christ was a total failure!
Because what Christ did with out sins on the cross affected our past, present and future sins(Heb 7:27, 12, 26, 9:24-26)! We of this genetration believe that Christ died 2000 yrs ago for us to be saved. We were not present then, but we believe that what he did at the cross, was powerful enough to affect us 2000 yrs later. But we find it very hard to believe that our sins were taken care of even before we get to commit them 2000 yrs latter!!!! Christ is far far far greater that Adam!! His saving grace can in no way be compared to the fall( Rom 5:12-21)!!
By the way the passage you quote 1Jn1:8; yes I agree with the context but you have just used only one of the 4 principles of of interpretation. How about the historical context; how about the audience to which this epistle was addressed to and what actually caused Apostle John to write the epistle in the first place. John wrote this epistle to fight Gnostics who had infiltrated the church after Paul's martyrdom( check out on what Gnostics believed pls). if we get to study diligently( by applying the 4 principles of hermineutics) , there is a lot I believe, that we will understand in detail . Let me just give one example, between Genesis chapter 11 and 12, lies 1500 years of bible history. So if we rely only on the bible alone, we will never know the full history of the bible!
