"The reason why the Christian life is so hard, is so difficult, is because we can't help but fight them [sins]; not because we're good but because we're in Christ; because we're new creatures. That's what's so hard about the Christian life. On the basis of God's action we're called to action. But it's not to complete Christ's mission. It's to come to terms with Christ's mission and work every day. What Paul is saying here is stop letting sin bully you. Stop letting sin push you around. 'For sin shall not have dominion over you, for you are not under law, but under grace.'"-- Michael Horton commenting on a portion of Romans 6.
