8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
No, I’m not a sinner. Yes, I am a sinner. But… I’m a sinner saved by grace. Now wait a minute; I’m saved. I do not sin anymore. If I sin, that proves the Holy Spirit is not in charge of me. And if the Holy Spirit is not in charge, then I am not saved. In fact, I am lost. If I am lost, then I am a sinner.
And so on. Circular reasoning?
The author of 1 John writes that “if we say we have no sin, we deceive ourselves.” He adds that “if we say that we have not sinned, we make [God] a liar.”
If we claim to be sinless, “[God’s] Word is not in us.”
What we are to do is:
1) Recognize that we are sinners.
2) Confess our sins which we fall into each and every day.
3) Trust that God forgives these sins and make us righteous by His sacrifice.
