Thank God that you are no longer under the dispensation of the law. By virtue of the sacrifice and victory of Jesus sin is no longer your master once you accept Jesus as Lord and Savior. At that point you have been translated from the requirements of the law to the freedom of grace.
Friend you have been set free. You no longer have to live in fear of sin. Rather approach every sinful condition with confidence based on God’s word that sin has no dominion over you – Rom 6:14. Once you became born again you lost your status as a sinner.
You are now a child of God empowered to live above sin. You may stumble from time to time but this doesn’t change your eternal status. Rather dust yourself off and try again. As you apply the word of God in that situation and keep pressing in you will overcome that sin. Your freedom is a reality; walk in it.
