You are not your own.

What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.

1 Corinthians 6:19‭-‬20 KJV

Now this chapter involves dealing with issue with fellow Christian's and not with unbelievers, but these verses play an important role in every saved person's life.

If you have confessed and has been saved and baptized then you are not yourself. You are not seen as (insert name here) the sinner. When you were you became Christ. You body was bought by Jesus by way of the cross. He took a beating, he took being humiliated. He took death for you. You are no longer your own person. You are his body now on earth.

That may seem intense, but there is a beauty in this, you are seem as a sinless perfecting being by God. So remember that whenever you are out in the world. You are the temple of God and what you do is for his Glory.
