OP: Sin has no more dominion over you.
Rom 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
(NOTE Sins dominion is DEATH. God's gift thats given those who trust in Jesus sin payment & resurrection is eternal life)
Jesus resurrection is proof he conquered sin & death: Acts 2:24, 2 Tim 1:10 Rev 1:18. Not only for himself, but, for all that believe in his sin payment & resurrection 1 Cor 15:20
The books of Rom & 1 Cor, are written to believers: Rom 1:6-7 & 1 Cor 1:2
1 Cor 15:56 The sting of death is sin; and the strength of sin is the law.
(NOTE: Through the law, sin is exposed & it condemns)
Rom 6:14 For sin shall not have dominion over you: for ye are not under the law, but under grace.
(NOTE: Sin no longer has dominion over the believer. Believers in Christ sin payment & resurrection, are no longer under the law, their now under grace).
1 Cor 15:
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
55 O death, where is thy sting? O grave, where is thy victory?
Rom 6:14 Isn't saying a believer will never again sin. Jesus conquered sins domain DEATH. And ALL of the believers sins have been forgiven/removed/washed away! Sin is the transgression of the law (1 Jn 3:4) once the sin is removed there in no transgression.
1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
(NOTE: The Adamic sin nature is in us all. Until 1 Cor 15:54 above is realized. Soon very Soon! We will all stumble)
1 John 2:1 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:
(NOTE: Every believer that sins (we all will) has a righteous High Priest (Heb 4:14-15) that advocates/speaks on their behalf)
Rom 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe:
(NOTE: Jesus took ALL the believers sins onto himself. Our High Priest (Heb 4:14-15) also imputes his righteousness onto everyone the believes in His faithful, obedient sin payment & resurrection. Also see Rom 4:8 11, 22, 23, 24. And we bebome the righteousness of God in Christ 2 Cor 5:21)
Salvation isn't about how sinless, great & obedient we are. It's about how sinless, great & obedient our Savior is!
