No, you're still confused if you think that sinning is a witness of Christ.
You really have a problem with reading comprehension don't you.
I have never said nor have I even suggested that sinning is a witness of Christ.
You are the one claiming sinless perfection.
John said that if we say we have no sin we call God a liar.
I strive every day to overcome temptation and do God's will.
I fully understand that from time to time I sin. Always will as long as my spirit lives in this flesh.
It hurts when this happens. It tears me up because I have failed my Savior.
I ask and receive His forgiveness.
But unlike some, I do not call God a liar by saying I never sin.
