1Jn 2:1-2 KJV
(1) My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
(2) And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
sin doesn't affect God's presence in the reborn believer at all, but focus on sin can affect your perception/realization/awareness of God's faithful, continuous, loving presence in you. sin isn't a problem for God at all - as Jesus, He has paid for the sins of the WHOLE WORLD, lost and reborn alike. God isn't relating to you according to your flawed performance, but according to His perfect performance as Jesus; He's looking at the intent of your heart. it's almost too good to be true - gospel!
Heb 9:13-14 KJV
(13) For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
(14) How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
you have to renew your mind with His word to shift your focus from your performance shortfalls to your heart-intent - which is to say to 'retrain' your conscious with His word so that it's not focused on your performance but on your heart's intent. when you set your heart to be led by God rather than your own intellect and experience, the devil will stop trying to push you back into sin - he'll run around to your back and start pushing you into self-condemnation over sin; the more you reduce sin in your life by your own strength and understanding, the more he will focus your attention on the sins you haven't overcome yet - he wants to stop your faith and help you to leave this life as quickly as possible to minimize the impact you might have on others to help them understand God's limitless goodness and faithfulness - stop helping him by re-focusing on being led by God, using His word as the way to confirm His leading rather than the set of 10,000 or so rules that you must apply and obey correctly in each situation according to your own strength and understanding. it's not your job to 'stop all that sinning'; your job is to learn to be led by the Spirit of God, the Holy Spirit, that lives inside of you - and the more effective you become at being led by God, the less you will transgress His laws - as He will never lead you to sin.
God's forgiveness has already been given to everyone, but only those who receive it as a free gift, regardless of their performance, will benefit from that forgiveness. the essence of sin is not believing God about something - all transgressions of His laws are the birth of this conception of unbelief - if you don't believe you were forgiven of ALL you sins (past, present and future from your current perspective in time) some 2000 years before you were born, then you will find yourself on a tread mill of condemnation that accelerates the more you try to 'stop all that sinning' and keeps you going nowhere in your spiritual walk.
Col 1:4-17 KJV
(4) Since we heard of your faith in Christ Jesus, and of the love which ye have to all the saints,
(5) For the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel;
(6) Which is come unto you, as it is in all the world; and bringeth forth fruit, as it doth also in you, since the day ye heard of it, and knew the grace of God in truth:
(7) As ye also learned of Epaphras our dear fellowservant, who is for you a faithful minister of Christ;
(8) Who also declared unto us your love in the Spirit.
(9) For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding;
(10) That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God;
(11) Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness;
(12) Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
(13) Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
(14) In whom we have redemption through his blood, even the forgiveness of sins:
(15) Who is the image of the invisible God, the firstborn of every creature:
(16) For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
(17) And he is before all things, and by him all things consist.
notice that God has already done all He needs to do - but you must believe Him to benefit from what He's already accomplished.
for example, when will you believe that you're already forgiven for all your sins (past, present and future)? now according to His word, or when your performance is flawless? what is your decision based on - His word or what you perceive with your 5 senses (such as your imperfect performance)? when will you believe that you've already been delivered from the power of darkness of Aspergers? now according to His word, or when you no longer see symptoms, or when a doctor tells you this? what is your decision based on - His word or what you perceive with your 5 senses (such as symptoms and doctor's reports)?
Rom 4:13-22 KJV
(13) For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.
(14) For if they which are of the law be heirs, faith is made void, and the promise made of none effect:
(15) Because the law worketh wrath: for where no law is, there is no transgression.
(16) Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,
(17) (As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were.
(18) Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall thy seed be.
(19) And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:
(20) He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
(21) And being fully persuaded that, what he had promised, he was able also to perform.
(22) And therefore it was imputed to him for righteousness.
