We need to remember that when we bring the grace of God to people that it always comes with blood on it for a reason!
To speak of grace without sin is no better. To do this is to trivialize the cross of Jesus Christ, to skate past all the struggling by good people down the ages to forgive, accept, and rehabilitate sinners, including themselves, and therefore to cheapen the grace of God that always comes to us with blood on it. What had we thought the ripping and writhing on Golgotha were all about? To speak of grace without looking squarely at these realities, without painfully honest acknowledgement of our own sin and its effects, is to shrink grace to a mere embellishment of the music of creation, to shrink it down to a mere grace note. In short, for the Christian church (even in its recently popular seeker services) to ignore, euphemize, or otherwise mute the lethal reality of sin is to cut the nerve of the gospel. For the sober truth is that without full disclosure of sin, the gospel of grace becomes impertinent, unnecessary, and finally, uninteresting.
