We begin the path by justification or freedom from the penalty of the law, we end the path in sanctification.
Seeking justification through the lesser law is a trap. If we fail in one point, we have failed in all.
"For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all." (James 2:10)
Self justification via comparison: "At least I'm not as bad as so-and-so":
"And no unclean thing can enter into his kingdom." (3 Nephi 27:19)
