Salvation in Christ is not essentially about sin. God does not save you because you throw away your sin, or because you are able to stop sinning. Salvation is about your yielding to Him in repentance. Big difference.
Saying no to Jesus is a dead faith with dead works
God calls His followers to reject sin (2 Corinthians 7:1), all that He calls “sin”, and press on to our upward calling (Philippians 3:12-14). Fake faith does not fool God.
Being a Sinner
Being a sinner is actually quite humiliating, isn’t it? (I assume you also are… and can relate?) I did not want this. I did not plan this. I did not want to be in this. So what do you do about it? My ambition in life – is to please my God. So, this sinning is not what I want. And yet, I still sin! The thing is, though God saves us in an instant, maturity is a lifelong process that takes time. We have to learn to take it as it comes – and look to Christ moment by moment. We don’t accept the sinning, but we accept that we are weak and in need of the power of God in our life!
