We don’t confess our sins and ask for forgiveness for each sin in the flesh, every time we sin, in order to be forgiven at that moment for that sin. We’re already forgiven of our sins the nanosecond we believe the gospel, and all our sins are removed from us “as far as the East is from the west”.
Our sins are also forgotten the nanosecond we believe the gospel, so why keep reminding God of sins that were already dealt with on the cross?
When God looks at us, He is perfectly pleased with us, as He sees us with the imputed righteousness of Christ. Our sinful flesh has been crucified and buried with Christ. It’s dead. He doesn’t look at our dead, outer flesh’s performance…He looks at our renewed inner man that’s been reborn, made perfect and cannot sin because it has been born of incorruptible seed.
We don’t lose fellowship either every time we sin in the flesh. If that were the case, no one would ever have fellowship with God. Again, our sin was dealt with on the cross – God’s righteous wrath, punishment and anger was poured out on Jesus on the cross. It was dealt with. We’ve been declared justified – He’s not going to bring it up again every time we sin in the flesh.
Scripture says in 1 John 4:18 — There is no fear in love, but perfect love drives out fear, because fear involves punishment, and the one who fears is not perfected in love.
If we were to lose fellowship with God and be punished every time we sin in the flesh, we would be living in fear, because fear has to do with punishment. But per the above scripture, we are to be made perfect in love, which casts out all fear, because there is no fear (punishment) in love.
While our inner man (us a soul and spirit) has been reborn of incorruptible seed, made a new creation, kept from stumbling and cannot sin, our unregenerate outward man (the sinful flesh) still sins. We are exhorted, encouraged, asked to, pleaded with and begged to possess our flesh in a manner of holiness, not using our liberty from freedom from the law in regards to salvation to indulge the sinful passions and desires of the flesh. However, this is not for salvation. It’s for a joyful and peaceful life on this earth.
