One scripture impressed me a couple days ago. It is Alma 6:13.
"For the Lord suffereth the righteous to be slain that his justice and judgment may come upon the wicked; therefore ye need not suppose that the righteous are lost because they are slain; but behold, they do enter into the rest of the Lord their God."
The Book of Mormon is so plain, teaching that God does not deny the agency of man to maintain temporal justice. If people make bad choices, it reflects on them. God's justice is not served immediately, and life is not fair in many temporal situations; however, God is just. Be faithful to him, and he will fulfill his promises unto you.
