This was an attempt to mix ingredients of the law into the provision of grace. To do this indicates a very poor understanding of God's grace. For some reason, it seems like God’s grace is so very hard to wrap our heads around. We, as humans, are wired for qualifying and quantifying. Almost all aspects of life are charted and measured. So, it is very natural for us to think that, even when it comes to grace, there must be things that require measuring the quality and quantity.
