Many people talk about others saying they are sinners, but in reality we are all repentant sinners before the almighty God. The fact that we are in the way of the Lord does not take away from us that we are sinners, the only thing that changes is that people turn from their evil ways and repent of them and turn to the ways of the Lord.
If we claim to be without sin, we deceive ourselves and the truth is not in us.
1 John 1:8
Something we must keep in mind is that people who say they have no sin are not in the truth as the Word says because every day we must ask the Lord to free us from all sin and every day we can ask God to forgive us.
