GOD's grace: passing over the condemnation rightly due us and dwelling with us in mercy that we may become like him.
So then how do we become like him if we don't actively try to be better? You make God sound like an enabler. Sin is addictive and if we are passive about breaking the cycle then we are telling satan that he has won. But if we take a hold of the spirit and use that as a leg up in beating sin (as opposed to expecting the spirit to do all the work) we can beat it, not in its entirety but our hearts will change and we will start to be digusted with our old ways and want to avoid them like the plague. I have seen this change in myself. I have seen myself start to hate my sin and not be so complacent. We can't expect God to do all the work for us. We have to resist temptation with everything we've got. Ya win some and ya lose some but you don't stop fighting, ever. Because once you say, "oh i'm covered by grace" you have given yourself permission to sin" and God has never given us permission to sin, not even under grace.
