In order to render a response to the question asked, it is vital to review the entirety of Scripture and not just verses extracted out of context.
Christians serve a God who is “rich in mercy” and continually proves His “great love for us.” He has made every Born-Again Christian “alive with Christ even when” they “were dead in transgressions.” It is by His grace that they “have been saved.” There is absolutely nothing they could ever do to be worthy of it. The wondrous heavenly Father has “seated” them “with him in the heavenly realms in Christ Jesus” (Eph. 2:4-6).
Mankind is now dead in their sins because of Adam. But in Jesus, they are made alive! To be “alive in Him” means that they are dead in their transgressions because it is "by His grace we have been saved" (Eph 2:5). It is only by His grace and not by anything they could ever do. Since they “have been raised with” Jesus, their life is now “hidden with Christ in God.” They must now set their “hearts on things above, where Christ is seated at the right hand of God” (Col. 3:1-3).
When a Born-Again Christian sins their justified position before God stays the same but their condition at that moment is changed. If a husband or wife hurts the other and does not apologize or repent of his or her mistake, their condition, or relationship, is harmed, even though they are still just as married as when they were in newly-wedded bliss. In the current legal system, the only way the behavior could change their position is if they both mutually agree to get a divorce.
"My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense - Jesus Christ, the Righteous One." (1 John 2:1-2)
The intercession of Jesus assures them that they have forgiveness. "In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit Himself intercedes for us with groans that words cannot express" (Rom 8:26).
When a Born-Again Christian sins, Jesus is always interceding on their behalf before God, the Father. Their relationship with Jesus is based upon what He has already done for them, not what they have done for Him.
“I give them ETERNAL life, and they shall NEVER perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand" (John 10:28).
In the past of the Born Again Christian “He chose" them "in him before the foundation of the world, that we should be holy and blameless before him. In love, he predestined us for adoption as sons through Jesus Christ (Eph 1:3-14) and sealed them with the promised Holy Spirit.
In the 'present' of the Born-Again Christian, they "have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose (Eph 1:7–9). If they are left in their sin, then they are separated from God. Only the single one-time sacrifice of Jesus can bring the holy God so close that He never leaves.
In the 'future' of the Born-Again Christian, the Holy Spirit is the guarantee of their "inheritance until" they "acquire possession of it, to the praise of his glory" (Eph 1:9–14).
When the Born-Again Christian confesses their sins, “He is faithful and righteous to forgive" their "sins and to cleanse" them "from all unrighteousness” (1 John 1:9).
God does not count their sins against them after they believe in Jesus Christ. They will never be condemned in the future. They were condemned before they believed in Jesus, but not after they believe. From a logical observation, Jesus died to forgive all sins in the past before anyone was born today, which would seem to indicate that He died for all future sins, including those that happen after a person becomes justified through conversion.
“Therefore there is now no condemnation for those who are in Christ Jesus.” (Rom. 8:1)
The Born-Again Christian is a "Good Tree" and they habitually walk in the light of God. A "Bad Tree" habitually walks in darkness, and they never had true fellowship with Jesus (Luke 6:43-45). The Born-Again Christian walks in the light, and they are cleansed from all sin and unrighteousness because they are filled with the righteousness of Jesus (Phil 1:1). The "Bad Tree" is NEVER cleansed from all sin because they have never confessed to committing sin before a Holy God, which is why Jesus says He NEVER knew them (See 1 John 1:5-2:6).
The Born-Again Christian does conditionally sin because they are still a sinner, but now saved, justified, and sanctified positionally in Christ, and has “an advocate with the Father, Jesus Christ the righteous. He is the propitiation (Gk:”hilasmos” = atonement) for" their "sins, and not for ours only but also for the sins of the whole world."
“And by this we know that we have come to know him, if we keep his commandments. Whoever says "I know him" but does not keep his commandments is a liar and the truth is not in him (i.e., Bad Tree), but whoever keeps his word, in him truly the love of God is perfected (i.e., Good Tree). By this we may be sure that we are in him: whoever says he abides in him ought to walk in the same way in which he walked.” That is why ‘there is no condemnation for those who are in Christ" (Rom. 8:1).
Forgiveness has two aspects. One is the justification and regeneration of judicial forgiveness God grants as Judge. It's the forgiveness God purchased by Jesus atonement for sin which frees them from any threat of eternal condemnation because it is immediately complete. Everyone “who believes in Him receives forgiveness of sins (Acts 10:43; 13:38; 1 Jn 1:2).
The other aspect is relational forgiveness God grants as their Father (as in the marriage analogy). He is grieved when His children sin. The forgiveness of justification takes care of judicial guilt, but it does not nullify His fatherly displeasure over one's sin. He chastens those whom He loves, for their good, and deals with the conditional consequences of sin via the throne of grace because His merciful kindness leads to repentance (Heb. 12:5-11; Rom 2:4).
The Bible reveals in a very practical sense, God's divine displeasure with one's daily sins and demonstrates His love for them through discipline (training) and reproof (Heb 12:5-11).
A healthy Born-Again Christian shows conciliatory remorse over sin through daily confession, and a continual attitude of repentance so that they are conditionally purified and cleansed from the consequences and effects of sin.
"If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness" (1 John 1:9).
The Born-Again Christian is forgiven, not because they are actively confessing their sins each day, but because God had declared them to be perfect and alive positionally, and no longer dead, the moment they became Born-Again (Eph 2:4-6; Col 2:13, 1 Jn 2:12; Eph 2:4-6). The Greek word for ‘forgiven” is ‘aphiemi,' a perfect participle which refers to something that has occurred in the past and is continuing into the present. This means that all of the past and present sins of Christians have been forgiven – period! They will never be remembered again.
God could not declare the Born-Again Christian as absolutely perfect if they still sinned positionally in His eyes. God treats them as if they were perfect even though they are still a sinner conditionally.
Positionally in God, the Born-Again Christian is sitting with Jesus in heaven spiritually, even though they are physically here on earth. God is saying that, after a person believes in Jesus Christ, He considers them to be saints and already citizens spiritually seated in heaven. They are spiritually alive! He ignores their present condition and considers them to already be positionally in heaven. This is called ‘position’ versus condition (i.e. practice).
The Born Again Christian is a love gift from the Father to the Son “All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out’… all that He has given Me I lose nothing, but raise it up on the last day” (John 6:37-39).
Jesus is saying that everyone who truly believes in Him will be raised up on the last day and go to heaven. He will not lose anyone, and He will not cast out anyone who has become Born-Again, which means, once a person truly believes in Jesus, God takes control of his/her life and does not see their sin because of their position in Christ who lives in them. They are now His Holy of Holies and have been sanctified by the single and final offering of the shed blood of Jesus (Heb. 10:14).
Salvation is not based upon any works a person could do; it is based upon the works that Jesus has already done. He forgave the sins of mankind - past, present and future on the Cross as a once-and-for-all sacrifice because He is the Great High Priest, who is “the same yesterday, today, and forever” - and the ultimate sacrifice for the forgiveness of sins, and every Born-Again Christian has become His holy, royal priesthood, offering spiritual sacrifices acceptable to God (Heb 13:8). It is up to the person to appropriate His forgiveness by becoming Born-Again.
The Born-Again Christian is hidden “in Christ" (1 Peter 5:14; Phil 1:1; Rom 8:1) and they have “died, and their "life is hidden with Christ in God" (Col 3:3), and He exchanges their sin nature for His righteousness (2 Cor 5:21). The Born-Again Christian cannot remain as they were and enter into the presence of a holy God "For as many of you as were baptized into Christ have put on Christ." (Gal 3:27)
The Bible says that in their natural, sinful state they are enemies of God, but in Jesus, they are welcomed into His presence as His children (Rom 5:10; John 1:12; Gal 3:26). No one can come to God on their own merit. They must be escorted by the Son.
No amount of self-cleansing can make a person pure enough to warrant the attention of perfection. What this means is that God, the Father, no longer sees the sin of the Born-Again Christian; He sees Jesus, God, the Son, who lives in their spirit, mind, and body, and also sees His righteousness instead because they are in Christ and their sin debt canceled, their relationship with God restored, and their eternity secured (Eph 2:13; Heb 8:12; John 3:16-18; 20:31).
