That statement contradicts 1 John 1:8-9 and 2:1-2. Note that John was addressing Christians.
"If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (1 John 1:8-9).
"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: And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world" (1 John 2:1-2).
We wouldn't need an advocate if we are sinless neither would we need to confess our sins.
Firstly, lets consider God's definitions of "sin".
Scripture says that christians have
"ceased from sin" (1pet 4:1),
"cannot sin" (1John 3:9).
This is
not however, referring to our behavior, as the physical is not perfect.
Remember that in Christ we are justified by faith, hence Satan, the accuser, can no longer charge us with sin.
Rom 8:33
Who shall lay any thing to the charge of God's elect? It is God that justifieth.
Below are a few examples of God's definitions of sin that will show why Christians cannot be charged with sin:
Unrighteousness, 1John 5:17 (Christians are righteous in Christ, so in this regard we do not sin)
Unbelief in Jesus, John 16:9 (Christians believe in Jesus, so in this regard we do not sin)
Trangression of the law, 1John 3:4 (Christians are
not under the law, so in this regard we do not sin)
Regarding sin/transgression of the law, Christians cannot be accused of this sin as we are not under the law of sin and death.
The law of the Spirit of life in Christ Jesus
sets free from the law of sin and death, (
Rom 8:2).
"Christ is the end of the law for righteousness," Rom 10:4.
Also note Ga; 4:25, Gal 5:18, 2Cor 3:7-9 and 1Tim 1:9
Regarding the law of sin and death it should be noted that:
“whatever the law says it says to those who are under it” (
Rom 3:19).
“the law was not made for a righteous person (Christians), but for…the ungodly and for sinners” (
1Tim 1:9).
“where there is no law there is no transgression (SIN)” (
Rom 4:15).
Only our
past sin was dealt with at the cross.
Rom 3:25:
"Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past,"
It was
only our
past sins that were forgiven. That means there is
no more forgiveness of sin after this as sin was finally dealt with at the cross. Christ's sacrifice totally purged/cleansed us of sin. After that there is
no more subsequent sin because our righteousness is not judged by deeds of the law anymore. Instead our faith is counted for righteousness, Rom 4:5.
When we are in Christ, believing in him, then we are righteous (Rom 4:5), sanctified (Heb 10:10), holy (Rom 11:16) and perfected (Heb 10:14), hence Satan, the accuser, cannot charge us with sin, Rom 8:33.
Consider also 1Pet 4:18
“If the righteous scarcely be saved, where shall the ungodly and sinner appear”.
Clearly there are 2 different groups described here.
Group 1: Righteous (and saved).
Group 2: Ungodly/Sinner (unsaved).
Either we are righteous (in Christ)
OR we are sinners. We
can't be both.
In Christ we have
"ceased from sin", 1Pet 4:1
How have we "
ceased from sin?
We believe in Jesus, thus our old man has been crucified with him, Rom 6:6.
Now, I no longer live but Christ lives in me, Gal 2:20. And in Christ there is no sin, 1John 3:5
1Pet 4:1
“Therefore, since Christ suffered (crucified)
for us in the flesh, arm yourselves also with the same mind (our old man crucified with him. Rom 6:6),
for he who has suffered in the flesh (Rom 6:6)
has ceased from sin”.
And this is also confirmed by 1John 3:9
“Whoever has been born of God does not sin, for His seed (Christ) remains in him; and he cannot sin, because he has been born of God”.
Truly Jesus set us
free from sin (
John 8:36).
On a separate point, regarding our obvious physical failings/wrongs, we will not profit in doing them. Although our righteousness is
not determined by this, there are physical consequences for any wrongs we do. Consider King David with his adultery/murder. He was disciplined by God.
But in regards to our righteousness, our faith is counted for righteousness, Rom 4:5.
We are born of God (1John 5:1) and cannot sin (1John 3:9). So Satan, the accuser, cannot charge us with sin, Rom 8:33.
