Does God's Election Lead to Spiritual Laziness? (COD 1, Arts. 12-14; Romans 12:1-3)

One would think that if we are assured that Christ's work is enough then it would cheapen grace. It seems that we would think there is no need to desire good works because we have already attained it all in Christ. How can our assurance of faith bring us to a place where we want to bring forth good works? How can Christ's work compel us to want to live for him instead of self?
