Alma provides his listeners (and us, as readers) with a kind of spiritual checklist of ways to discern true conversion. People who’ve experienced a mighty change of heart try to keep themselves blameless by being humble (verse 28), avoiding jealousy (verse 29), and refraining from mockery of others (verse 30). They feel that if they were to die today, they would die “sufficiently humble” in the knowledge that Christ has redeemed them from their sins (verse 27).
