I recommend reading all of Romans 6, actually I recommend the whole bible! A :D You are capable, you are able, you can still change, the Lord will pick you up and clean you, he will not leave you, nor forsake you. He still wants you to repent. You can do this through Christ!
The first one is talking about God's will, while the second talks about how we should live a holy and great life! If you need help to change, or need prayer. I will try my best to help :) Always remember Jesus Loves You! You can always accept Jesus as Lord and Savior. God is with you always :D
