I don't believe you. Show me your ticket.
You are either lying or you're deluded - every believer is tempted to sin at some point. Grace does not restore your fallen nature into sinless nature, not in this life, anyhow.

You're highly judgmental, brother, which makes me question both your heart and your agenda. What is up with you? It seems to be more personal than theological?
You want me to produce an actual "ticket" proving my salvation? What's up with that? Why don't you provide me with a drivers license indicating you really exist?
Salvation is the creation within us of a new nature by the gift of Christ. Our proof is in our attitude, our character, our good will inspired by Christ himself, because he lives in us and energizes us, and produces good fruit within us. As a Christian you should know all this.
So I'm wondering about your own spiritual welfare? What are you missing?
Yes, we all have a sin nature. But when we receive the new nature that comes from Christ, that nature is of surpassing power in conquering our lower nature. If we don't look at the temptations to sin, we may pursue righteousness, which is exactly what we chose to do when we pursued our new nature in Christ.
Having chosen it, and having experienced it, it is all we want. Only looking at temptations can throw us off. And since they are all around us, we have need of encouraging one another--not attacking one another, not judging one another, or suspecting one another.
But you evidence a real problem. And if there's something you need, rest assured you have access to Christ if you want that.
