When we walk in the Holy Spirit-no! But If we choose to walk in our flesh- we sin!
In Baptism you are Regenerated unto Newness of life in the Spirit, you are dead to the Flesh through Baptism.
From the moment you are Regenerated you are alive in the Spirit, and Walk in the Spirit from then on.
How do you walk out of your life in the Spirit, and walk in the Flesh if you are dead to the flesh, and then turn around and walk in the Spirit again?
We still sin and fall short. Some things we do not even know are sin yet- because God has not brought us to that place in our life where we can jettison that sin.
You as a Born Again Child of God Cannot Sin because.
1 Jn. 3:9
Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
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.
Sin in the Flesh of the Believer is destroyed through Jesus.
The Flesh of the Believer is Dead because of Regeneration.
The Born Again Believer is dead to Sin, the Law, and the Flesh.
Dead Flesh cannot sin, because it is not accountable to the Law.
God perfected us forever at the moment of salvation, but now He is making our lives gorw to match what He did! that is called sanctification.
Having been perfected forever at the moment of salvation, we cannot sin, we ARE, Have Been Sanctified, and Justified upon our Salvation.
Act. 20:32
And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among
all them which are sanctified.
Act. 26:18
To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among
them which are sanctified by faith that is in me.
