@JesusIs4Me,
I can't learn anything without you showing me scripture that God tells me "He is" imputing sin unto me as a believers. I can show you that God said He is "NOT" imputing sin unto a believer but has given us His words of being reconciled unto Him.
Rom 4:8 Blessed is the man to whom the Lord will not impute sin.
2Co 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
2Co 5:20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
2Co 5:21 For he hath made Jesus to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Ask the Lord to help you at least understand what I am sharing with you, even if you still disagree with it. Ask Him if the word shared is from Him.
What you are talking about where God does not impute sin is about that foundation which was laid by Jesus Christ. That foundation can never be removed; hence His seal as in the Holy Spirit can never be taken from you; that is His promise of eternal life with God. Ephesians 4:30 KJV & John 6:39-40 KJV
However,
what you BUILD on that foundation will be judged by whether or not you will be received as a vessel unto honor by looking to the author & finisher of your faith to help you lay aside every weight & sin to be received by Him.
Those who do not repent of the wood, stubble, and hay, which is the iniquity, the works of the flesh, as in sin, that defiles the temple of God, will be disqualified and thus denied entrance to the Marriage Supper in Heaven; think of it as temporary excommunication; the loss of the reward of crowns, the loss of being partakers of the firstfruits of the resurrection, the loss of having that mansion in the city of God.
Now what does that mean to those unrepentant saints left behind? The sins on that foundation will be burned away so that all that remains is His work; that foundation which was laid by Jesus Christ so they shall be resurrected later on after the great tribulation to serve the King of kings from all over the world in raising up the coming generations in the millennium reign of Christ.
That is HOW God does not impute sin against believers because
sin no longer have the power to separate us from God to put any believer in that hell which in turn will eventually be put in that lake of fire forever which is the second death; eternal separation from God.
BUT unrepentant sin on that foundation CAN disqualify you as any iniquity that denies Him as Titus 1:16 testifies will wind up having Him deny you as in disqualifying you from attendance to the King's Supper because you do not have to verbally deny Him, an unrepentant sin is denying Him for why Jesus said He knew them not in Matthew 7:21-23 as they were workers of iniquity.
That is what running that race is all about, looking to the author & finisher of our faith to help us lay aside every weight & SIN so that we may be received by Him as that vessel unto honor in His House to attend the Marriage Supper in Heaven. That is how we live that reconciled relationship with God through Jesus Christ as His disciple. That is why the crowns we receive are His crowning achievements in us for why we would cast them at His feet like the elders will in Heaven.
So sin is still sin even to a saved believer and although God will not impute sin meaning that sin on that foundation will NOT lose the saint's reconciled relationship with God, we are still accountable for how we build on that foundation. Unrepentant saints left behind will have those sins burned away off of that foundation, but that foundation remains testifying true to His words that God will not impute sin against us for He is with us always even when saints are not abiding in Him; yea, even former believers because He still abides in them even if they get left behind ( 2 Timothy 2:13 KJV ) for why even they are called to depart from iniquity before the Bridegroom comes; 2 Timothy 2:18-21 KJV
James understood that truth like Paul, for why he cautioned believers about temptations and how resisting sin comes with a reward of this kind of crown.
James 1:12
Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him. 13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: 14 But every man is tempted, when he is drawn away of his own lust, and enticed.
15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. 16 Do not err, my beloved brethren.
If we sin, we can ask the Lord for forgiveness ( 1 John 1:9 KJV ) and help us to continue to keep laying aside those weights ( provisions for the flesh ) that tempts us to sin as well as the sin itself to not continue in it ( Hebrews 12:1-2 KJV )
Otherwise, just seeing them as unfruitful works liable to have it remain on that foundation, defiling the temple of God, and that is not keeping your body which is the temple of the Holy Spirit, as a vessel unto honor. When sinning saints repent and depart from sins with His help, then they are purging themselves to be that vessel unto honor to be received by Him when the Bridegroom comes. If not, they will lose the rewards of crowns and be left behind where Jesus has to burn those sins off of that foundation for them so they can be received by Him when He comes as the King of kings.
Here is what Paul says in like-mindedness and same judgment as James;
1 Corinthians 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
Peter understood this as well.
2 Corinthians 5:8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord. 9 Wherefore we labour, that, whether present or absent, we may be accepted of him. 10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad. 11 Knowing therefore the terror of the Lord, we persuade men; but we are made manifest unto God; and I trust also are made manifest in your consciences.
Those unrepentant saints and unrepentant former believers left behind will suffer the coming calamity of fire on the third of the earth and the subsequent great tribulation, but He is faithful in keeping the souls of His unrepentant saints left behind because that is how God will not impute sin on them.
1 Peter 4:17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? 18 And if the righteous scarcely be saved, where shall the ungodly and the sinner appear? 19 Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator.
Do you want that crown of life? Confess your unfruitful works as sins and ask Him for help to lay aside every weight ( provisions for the flesh ) as well as the sins in running that race for that crown of life and to be received by the Bridegroom.
