No.
It’s a sign of growth as a Christian.
Same experience that Paul had...
1 John 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.”
If you believe a true Christian cannot stop sinning then you do not believe the Scripture. Read slowly and carefully what I have posted: Whosoever is Born of God doth not commit sin.
There is a false Christianity that teaches this is not true.
He who has ears to hear let him hear.
