Anyone who commits a sin resists the Holy Spirit, our guide and conscience. Do Christians ever commit sins?
If they do, then they are sinners.
A Christian is Dead to the Flesh
John 3:6
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Rom. 6:4
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.
A Christian is Dead to the Law
1Co. 15:56
The sting of death is sin; and the strength of sin is the law.
Rom. 7:6
But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
A Christian is Dead to sin.
Rom. 6:2
God forbid. How shall we, that are dead to sin, live any longer therein?
Rom. 6:11
Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
Not only so, but Jesus Destroyed Sin in the Flesh.
Rom. 8:3,4
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.
