Alma 13 has, for me, been a chapter about the Priesthood in general and how we became qualified in the pre-mortal life to be presented with the opportunity to receive it in mortality. I now see that this chapter also teaches about what is required to actually receive and then honor that Priesthood thereafter. Closely related to this is our need for the Savior and the important role of his atonement in our progress.
Verse 2 (and 16): How does the Priesthood direct us to Christ and his atonement?
Verse 3: What qualified us (in the spirit world) to be presented with an opportunity to bear the Priesthood (in the mortal world)?
Verse 10: What qualifies us to be have the Priesthood conferred upon us?
Verse 12: What does success look like for Priesthood holders?
Verses 13-15: So, what must we now do to enter into the rest of the Lord?
Verse 18: What did the greatest Melchizedek Priesthood holder do?
Verse 23-26: Why is this important?
The coming of Christ fast approaches!
Verses 27-31: What should we do?
Other scriptures to reference:
1 And now it came to pass that according to our record, and we know our record to be true, for behold, it was a just man who did keep the record—for he truly did many miracles in the name of Jesus; and there was not any man who could do a miracle in the name of Jesus save he were cleansed every whit from his iniquity...
37 That [the rights of the Priesthood and the powers of heaven] may be conferred upon us, it is true; but when we undertake to cover our sins, or to gratify our pride, our vain ambition, or to exercise control or dominion or compulsion upon the souls of the children of men, in any degree of unrighteousness, behold, the heavens withdraw themselves; the Spirit of the Lord is grieved; and when it is withdrawn, Amen to the priesthood or the authority of that man.

And may the Lord grant unto you repentance...that ye may not suffer the second death.
