Yes, yielding to God, fellowship, forgiveness, and salvation are linked together. This is what 1st John chapter 1 is saying. You can highlight fellowship all day long in 1 John 1 but yet you are still ignoring the words that say, "if we confess our sins, he is faithful and just to forgive us our sins." Again, you can't be forgiven of sins by confessing sins if your future sin is forgiven you by some kind of false OSAS belief. You either believe 1 John 1:9 or you don't believe it.
Again, if we cannot resolve this simple verse as it is written plainly, I am afraid it will do not good to argue with you on any other point in Scripture. I say this again, not to wound you but out of love for God's truth within His Word.
Forgiveness of sins is dealing with salvation and not exclusively fellowship alone. 1 John 1:9 says we are forgiven of sin. Forgiven of sin. We are forgiven of sin. IF.... we confess our sins. That is what it says in 1 John 1:9.
Jason, you are so hung up on an interpretation about having sins forgiven and cleansed by the blood after we have been saved. This has lead you to believe against OSAS and any claim that all sin has been forgiven (past, present and future) when we trust in the gospel and believe upon the Son. When we believe upon the work of the cross we have to agree with God that Christ came and was crucified to take and put away our sins and the sin of the world (John 1:29, Gal 1:4, 1 Jn 2:2, Heb 9:26). He accomplished this as a 'finished work' on the cross through the shedding of his own blood as the propitiation (or mercy seat) for our sins (Rom 3:25, 1 John 4:10). So far you agree with that, right?
According to (2 Cor 5:19-20) God was in Christ reconciling the world unto himself according to (Isaiah 53:1-11), not imputing their trespasses unto them... for this reason... all trespasses and sins, which are dead works (Eph 2:1, Col 2:13, Heb 6:1, 9:14), were transferred to the Christ's body on the tree (1 Pt 2:24 - cross). His soul was made an offering for sin and He bore all our iniquities. All sin, all iniquity, all transgressions and all trespasses had to be dealt with for all men, past, present and future, in all the world. No man and no sin could be left out for all had sinned and come short (Rom 3:23, 5:12). For Christ to bear sin for all men, it also had to be for all sin. To leave out a single sin, iniquity, trespass or transgression would make his sacrifice incomplete and he would have to be crucified over and over again for those not covered by the blood of the cross.
Jason, your problem is with any future sins committed by the believer after salvation and how should the believer look at and deal with those sins. Every believer who has been saved by grace through faith must walk in the same manner (Col 2:6). If Jesus took away the sins of the world as the lamb of God, and he did, then we must agree with that work of the cross and the shed blood that goes with it, because without the shedding of blood there is no remission of sins (Heb 9:22, Acts 10:43). Now where remission of these is, there is no more offering for sin (Heb 10:18) and we are sanctified by that offering ONCE (Heb 10:10). When this man (Jesus) had offered ONE sacrifice for sins FOREVER, he sat down at the right hand of God (Heb 10:12) and by that ONE offering perfected forever them that are sanctified (Heb 10:15) which the Holy Spirit is a witness (Heb 10:16). A done deed!
Now we can go to (1 John) and see what is being said about dealing with sin, if we sin. In (verse 4) these things are written that our joy may be full as a believer. Our fellowship with the Son and with one another is according to the light that we walk in. The light we have is the understanding that Christ bore our sins and remitted those sins through his shed blood. If we say (we may or may not) that we have fellowship with him and walk in darkness we lie and do not walk in the truth (1 John 1:6). This verse is troublesome because some think it refers to a saved person who has stopped walking in the light because of sin, while others think is refers to an unsaved person, who has never had the light to walk in. To get the full thought of what John is saying we have to include the remaining verses from 7-10.
John says, there are those who are saying they have fellowship but they walk in darkness, when fellowship is constituted by walking in the light. So those who are not walking in the light are not having fellowship as they assume, they lie and do not walk in the truth. These who profess to have fellowship, yet walk in darkness, how will they ever have fellowship in the light? How is that going to happen? The darkness they walk in is
skotos - a darkness resulting from blindness. It could refer to those who live in unbelief and are blinded by the god of this world lest the light of the glorious gospel shine unto them (2 Cor 4:4). It could refer to those who are blind not able to see afar off (2 Peter 1:9), who lack and are unfruitful in the knowledge of God and even forget that they they WERE PURGED from their old sins.
Those who walk in the light have fellowship with God and with one another who are in Christ. The blood of Christ is active and continually cleansing that believer of sins of omission, ignorance and those things they know nothing about because they have not grown in grace and knowledge enough to have the conviction to know those things. That is nothing new (babes in Christ). This would also include sins that one has never been engaged, partaken of or given place to, that could come up later in life. Those sins that we are being cleansed of, as we walk in the light, have to do with sins that have the potential to defile us that come from out of the heart (Matt 5:18,19). So God is using the word to penetrate and divide the soul and spirit to get into the thoughts and intents of the heart (Heb 4:12,13, 1 Cor 4:5) to deal with these issues of life (Prov 4:23) utilizing the blood to cleanse us from all sin and unrighteousness, the potential for corruption (Gal 6:8, 2 Pt 1:4, 2:12).
We can't say we have not sinned, for we would decieve ourselves in that, for that is not the truth that needs to operate in us, but we acknowledge our sin, by making a confession according to the conviction of the Spirit. This is how we begin to be restored in our fellowship of walking in the light and the blood now can once again be active and cleanse us from any and all unrighteousness that we have, whether by commission or omission or in the heart. This begins and takes place immediately when we believe in our hearts unto the righteousness of God through Jesus Christ and this is what (1 John 1:7 addresses). It continues to be active in the believer's life when he walks in the light and is being continually cleansed by the application of the blood and by the word of God's promises (Eph 5:26) to escape the corruption that is in the world through lust (2 Pt 1:4).
Salvation is being worked out and is never lost during this process of growing and being converted that we might have our hearts established in grace and our hearts sprinkled from an evil conscience (Heb 10:22) and yes, we can be saved by the blood of Christ and have sin active in our life, but not without the conviction of the Spirit coming into play, that we might be restored in our fellowship of walking in the light.
