"I will put my laws into their mind, and write them in their hearts..."

The Spirit of Christ is given to every man that he may know good from evil. (Moroni 7:16) I used to forgive others who messed up really bad by saying, "Well, they didn't know any better. They are not member of a church, they don't know Christ." Apparently that is not true. Even if they do not have or believe the Book of Mormon, the Bible states in Hebrews 8:10 "I will put my laws into their mind, and write them in their hearts..." So we are all held accountable to the same standard.
