Radical Grace/the Lutheran Difference

Once saved always saved. On the one people want to us to stop putting God in a box with all this talk of doctrine. But on the other hand they put God in a box by trying to hold some doctrine over God. As though God can be held accountable to a doctrine. Also Rick Warren and his own words about how Jesus makes up the difference between my good works and the perfection I need to stand before God and not be destroyed.
