"And ye will not have a mind to injure one another, but to live peaceably, and to render to every man according to that which is his due."
Mosiah 4:13
This is a good reminder of something that we will understand and feel if we are living close to the Lord. We won't want to injure anyone in any way, just like the change of heart that is spoken of elsewhere in the scriptures. Instead of having the instinct to harm, we can learn the instinct to love. The Lord is teaching us how to be amazing, awesome people, and if we just stick with him, we'll get there. :)
