I have wondered if people might not misunderstand John. When saved one gets credit through the Lord as if one had never sinned. Sanctification may make the temporal life a work in progress. One could compare temporal life to ram space in a computer where the imperfect, condemned humanity lives. Jesus converts imperfect character code of those with faith to perfection before allowing them onto the eternal SSD.
A program may be perfectly written, as it were, suitable for a Garden of Eden. Characters created in the program may be given free will and operating instructions. They disobey, and the program is given a correction to contain the free will virus run amock.
The free will virus may have good and bad characteristics. Good because it emulates some of the creative, inventive spirit of God, bad because it breaks the parameters of its own existence (as if a dog off a leash in a home near a freeway runs into eight lanes of high speed traffic). Interestingly sin of the unsaved and those with badly understood theology use global economics to move the world to an ecospheric brink
Before the program code of the characters is allowed into the eternal SSD of heaven the code must be corrected. God is perfect and imperfect code just won’t work in heaven. Jesus through His atoning sacrifice enters good code for each individual character subroutine who is saved so they can exist eternally with God through the Lord. Over time the code of each character is transformed like unto that of the Lord, who is perfect and fully God.
The saved do not want to sin though as imperfect beings probably do. They still have bodies that are reason enough for condemnation through original sin. Some have associated the liberal viewpoint of freedom to sin since Jesus is screening them from the penalty of sin viewpoint with a Gnostic heresy. If one cannot be credited with sin after being saved then, the reasoning went, why not use that as a license to sin. That viewpoint misunderstands the entire criterion of salvation.
Romans 6- 1″What shall we say then? Shall we continue in sin, that grace may abound?””2 God forbid. How shall we, that are dead to sin, live any longer therein?”
2nd Corinthians 4 “7But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us. 8We are troubled on every side, yet not distressed; we are perplexed, but not in despair; 9Persecuted, but not forsaken; cast down, but not destroyed; 10Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body. 11For we which live are alway delivered unto death for Jesus’ sake, that the life also of Jesus might be made manifest in our mortal flesh. 12So then death worketh in us, but life in you.
13We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak; 14Knowing that he which raised up the Lord Jesus shall raise up us also by Jesus, and shall present us with you. 15For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God.
16For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day. 17For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory; 18While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.”
