The more we fall in love with God the more we want to get rid of all sin in our lives, especially the habitual sins. That doesn't say we will never sin again, but sin will not be rooted. Love does not nurture sin, rather it is the destruction of sin.

I must know beyond the shadow of a doubt that God loves me. I must choose to love God in return so that in the power of the love I can deal with the roots of sin in my life, no matter how long it takes.

However, it is not enough to get rid of the root of sin; we must put on the mind of Christ. "Do not conform yourselves to this age but be transformed by the renewal of your mind, so that you may judge what is God's will, what is good, pleasing and perfect" (Rom 12:2) This too is a process that is not fully completed until we see God face to face.
