Notice that the first four defects that are to end, include "lyings, and deceivings, and envyings, and strifes." These are somewhat different than the next two. These first four are character flaws that lead to the next two.
The character flaws should not be thought of as defects in our ability to do business or conduct commerce. These are flaws leading to the failures of our redemption. Therefore, think of them as flaws in our beliefs, leading us to have what the Book of Mormon terms unbelief.
What lying goes on among us leads to priestcraft? How is our lying keeping us from knowing the Lord? What is it about our peculiar form of false belief that leads us to believe in, and spread about lying as part of the fallen, false faith we entertain?
What deceivings are part of our culture of unbelief? How is it we can celebrate the great priesthood "authority" we possess while acknowledging that it lacks any "power?" Are we deceiving ourselves? Are we alienated from God while thinking ourselves His peculiar people?
What envy is there among us? Has envy become a tool for church governance? If so, how does it become a tool for church governance? Have we built it right into our system at present?
Are we filled with strife? Is strife among us suppressing healthy exchange of ideas by labeling such discussion as "contention?" Is strife different from contention? Is uniformity of ideas and suppression of dissent something that will remove strife? If not, then why not?
These character flaws in turn lead to "priestcrafts" where people seek approval of the world but not the best interest of Zion. (2 Ne. 26: 29.) Do we want popularity from the "world?" What is the "world?" Why would someone practicing priestcraft seek in particular to have approval and lead the world? Why is the distinction made between the interests of Zion and the interests of the world? Is public relations always focused on approval from the world? If so, why are we seeking such approval? Does the world's opinion of us matter? Why? When have the followers of Jesus been popular? What have they suffered for His name? (Heb. 11: 36-40.)
Then we see "whoredoms" which we have discussed earlier. David Christensen's comment on the meaning of false religion is worth returning to read again in this post.
Then Christ sounds the alarm, attributing it to the Father. Repent. Come unto Christ. Otherwise you will be cut off. What does it mean to come to Christ? Read the short statement in D&C 93: 1. There is a succinct description of the process. You haven't come to Him until you have "seen His face and know that He is," or, in other words, until you hear from His own voice that He has atoned for your sins and He promises you a place in His kingdom.
All of these warnings are being given to orient you to what is important. The important thing is to come to Him. As Christ put it to Martha, "but one thing is needful." (Luke 10: 38-42.) Until we have come to Him, all our concerns about other matters must remain secondary. Of what good is it to know all mysteries, if we have not come to Him? This is why, in the middle of this warning of calamities to come, the Lord places this invitation to come to Him. He can help. He can restore and protect. But only if you are His.
