Not long ago a Latter-day Saint left this as part of a comment on Mormon Coffee:
“LDS people don’t believe that you are saved by grace, but by works.”
I’m sure there are some Mormons who would take issue with this Latter-day Saint’s statement of belief. In my experience, most of the Mormons I’ve corresponded with believe salvation (eternal life in the presence of God) is achieved by a combination of grace-plus-works.
Be that as it may, either idea (saved by works or saved by grace-plus-works) is recognized — within the bounds of historic, orthodox, biblical Christianity — as heresy.
For insight on the Christian commitment to salvation by grace through faith, watch this short excerpt of Pastor John Piper (3 minutes) explaining why God decided to save His people by faith alone.
You may ask, “Where, then, do good works come in? For God said we would be judged according to our works” (See John 5:29; 1 Corinthians 5:10). For insight on the Bible’s teaching on this, I invite you to listen to another excerpt from John Piper (4 minutes, MP3).
otherwise grace would no longer be grace”
