It's always good to hear that a believer in Christ Jesus considers himself to be a sinner.++++++So what you should do is stop calling believers sinners.
++++++That puts believers in the same category as unbelievers.
What I do do is tell it how it is, all believers still sin as do unbelievers with the difference being that unbelievers are not saved.
I suppose that's what Christianity has come down to these days.
Here's what the NT teaches:
Hebrews 5:9
9And having been made perfect, He became to all those who obey Him the source of eternal salvation,
° Jesus became the source of eternal salvation....to all those who obey Him.
Hebrews 12:14
14Pursue peace with all men, and the sanctification without which no one will see the Lord.
