What sin(singular), and sins(plural)? I have the righteousness of God in Christ.
Forgiveness/Justification in this dispensation
Believers in the gospel of Christ of 1 Cor. 15:1-4 have submitted themselves "unto the righteousness of God"(Romans 10:3). We now have the righteousness of God, Romans 3:21-25, 4:5, secured through the death, burial, and resurrection of the Lord Jesus Christ(1 Cor. 15:1-4). I have the righteousness of God: Romans 3:22-:26, 4:5, 5:1, 5:9, 5:17-18, 8:30, 10:3; 1 Cor. 1:30, 6:11; 2 Cor. 5:21; Gal. 2:16; Philippians 3:9
The LORD God has justified us forever because He sees us "in Christ": Acts 13;43; Romans 3:24-28, 4:25, 5:1,9, 8:30; 1 Cor. 6:11; Galatians 2:16, 3:24; Titus 3:7. This is an immutable reckoning in the mind of God. Justification is that judicial act of God by which, on account of the Lord Jesus Christ, to whom I am united("in Christ") by faith, He declares me to be no longer exposed to the penalty of the righteous requirements of the law, but restored to divine favor. I have been declared righteous. Justification is an act, not a process. Upon believing 1 Cor. 15:1-4, I was given a free gift(Romans 5:18)-a righteous standing before a Holy God. This gift, by definition, has nothing to do with what I have done or who I am. No amount of self-effort or good works could ever bring one to justification. I did not justify myself-it is God who justifies. This gift is unchanging. Once God declared me righteous on the merit of the eternal Son of God, the Lord Jesus Christ, the sin/sins question regarding me has been settled once for all.
Members of the BOC are reckoned to be: dead, crucified, raised, seated, glorified.
You cannot re-try a dead man, uncircumcize him, resuscitate him, unseal him, declare him "unadopted"...............
The sin/sins issue was settled 2000 years ago, and The LORD God is satisfied(propitiation). Religion is not.Believe the good news. Most reject it. And so it does....
