Many of us like to refer to ourselves as “a sinner.” Even pastors boldly proclaim at times, “I’m a sinner.”I would like to encourage you to stop doing that. Of course, you are a sinner, the Bible says “all have sinned and fallen short of the glory of God.” But, if you have been born again, 
then you have been made holy, and have been joined in union with Christ Jesus Himself. You are a new creation!
To continue to refer to yourself as a “sinner” after having been born again, puts your focus in a place that does a great disservice to the tremendous sacrifice that God made in giving His only Son to pay the penalty for your sins and my sins and the sins of the entire world.
There is great power in our words, and when you hear yourself refer to yourself as “a sinner” 
then your subconscious mind embraces that characterization of yourself, and chokes the life out of the reality of who you are after having been born again. Ask God to help you see yourself as you really are if you have been born again.
Change the way you talk about yourself and the way that you see yourself. Your subconscious mind will embrace the reality that you are the righteousness of God in Christ, and His grace will teach you to say no to ungodliness and help your behavior to come into alignment with the reality of who God has made you to be.
