What Does It Mean To “Repent Of Your Sins?”

In this episode Dr. Betters answers the question, "Jared asks, Hi Dr. Betters, I am 42 years old and blessed with a beautiful wife and 2 daughters. Around 2 years ago something changed in me and I started wanting to go to church to worship, I started praying and thanking God for my many blessings and feeling ashamed of my sins. My question is what does it mean to repent of my sins? There are a lot of people that say you must repent of your sins to go to heaven. There is also a lot of people that say we are saved by faith in Christ alone. To stop sinning all together is impossible and this scares me to face God on my last day."
