I think we as believers can be secure in our relationship with Christ. I'm not saying that sin isn't sin. I'm not saying that people should live in unrepentant sin. I'm not saying that that's a mark of a mature believer at all. Certainly if someone looks at my life, they will see that I have surrendered my heart, my life to Jesus Christ. I'll be very glad to tell them what my faults and my weaknesses are and the areas that I pray about in my life every day.
