It can be successfully argued that the Christian Bible (as opposed to the Hebrew Bible) preaches a religion based on grace not works. Since at least the Reformation there has been a tension among Christians between faith and works. The Book of Mormon clearly teaches the importance of good works. Mormonism leaves me with little doubt that relying on grace alone does not make the world a better place. And yes I think that is our job to do rather than just waiting for the Second Coming and expecting Jesus to fix everything.
