Once you have been filled with the Holy Spirit, He never leaves. Now there are people who say they are believers but they do not have the indwelling of the Holy Spirit. They pride themselves on how well they keep the law and they condemn people they think live sinfully. But Lord Jesus interceeds for believers who have the Holy Spirit indwelling them.
Romans 8:9But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God
dwell in you. Now if any man have not the Spirit of Christ,
he is none of His. (KJV)
There is no condemnation for those who walk after the Spirit, ( who are in Christ Jesus)
We are baptized unto His death, we walk in newness of life, our old man is crucified with Him so we do not serve ( at all) sin. The body of sin might be destroyed ( when we are the new man in Christ) so we should not serve sin ( so we do not serve sin but serve righteousness, and no man can serve two masters) as he that is dead is freed from sin ( Christ died to free us from sin and we die with Him to live again with Him without sin in righteousness)
Now righteousness is fulfilled in us ( any sin in us is not righteousness fulfilled in us)
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
7 For he that is dead is freed from sin.
Romans 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Galatians 3:27 For as many of you as have been baptized into Christ have put on Christ.
