That's an interesting point, I know there are many, many things that I rationalize or justify that falls in the idealized version of myself and wanting to repent of sin. I think most people would agree, but it's the conviction that drives us to repent and work to do better that generally runs afoul of our more flesh-based desires that is the hard, spiritual work. Just saying you believe Jesus died on the cross for your sins and everything else will work out and my will be done, is functional atheism, IMO.
Further, I don't and don't personally know anyone who hates browns or poors or gays or whatever. I think the right posture is one of compassion and an extension of God's love and mercy with a reminder of what God has decreed and wants for us.
It's "Where are your accusers? Go and sin no more.", not "Where are your accusers? Go and do whatever you want because I am love and you can abuse my abudnant grace."
