One of the beliefs of those against whom Peter is warning is a lack of historical perspective. Their attitude seems to be that, since God has not moved within living memory, He is unlikely to care much about what people do with their lives - hence the appeal to sensuality. Peter says that God's perspective is historical, not immediate and that He does not miss anything.

Introduction, parable of the laborers in the vineyard and the parable of the tenants. In each of these the question concerns eternal rewards and placement within the Kingdom. The disciples were curious as to what their reward would be. The laborers in the vineyard answers that question. There were also those who were trying to hijack the Kingdom. The parable of the tenants addresses their 'reward'.

Biblical leprosy is regarded as a spiritually caused disease infecting those who's behavior and speech damages the community. Over and over in Scripture one is urged to listen. Listen to God; listen to one's neighbors. On social media today, the art of listening seems largely to have been lost. This is to our harm, both as individuals and as a society.

In describing those who creep into the congregation and lead others astray, Peter says that one of their lures is the promise of freedom. This has always been the case with sin. In promising freedom from the restrictions of God's law, it holds out the promise of being a law unto oneself. While this is tempting, it eventually leads to ruin and death.

After the execution of Haman, the problem of his decree that all Jews be killed remained. Since that edict could not be changed, Esther and Mordecai got the King's permission to send a second decree to the effect that the Jews were allowed to defend themselves. That decree along with Mordecai's prominence effectively took the government bureaucracy out of the picture.

During the consecration of Aaron and his sons as priests before God, Nadab and Abihu offered profane fire before the altar and were themselves consumed by fire from heaven. Most commentaries focus on speculation about the two men's motivation in doing what was not commanded. Such speculation is completely irrelevant. What matters is what they did, not what they believed.

The first paragraphs in the chapter parallel Jude speaking of false teachers who infiltrate the body and entice the gullible into some sort of sexual sin. Their motivation is greed either for money or for influence.

There are ritual elements in the ordination of the High Priest that are repeated only by the procedure to cleanse a leper. That leads to some profound insights into God's plan for the redemption of His creation. (Inspired by Rabbi David Block at AlpehBeta.org)

Starting from a position of faith in Messiah, Peter urges believers to work on the content of their character. It is a strong character that will keep the believer from falling into worldliness and so becoming unfruitful. It is character that makes one's election sure.

Since Esther is not an expert in affairs of state, She would have no chance confronting Haman in the Throne Room. Instead she arranged to get the King into a situation where she had the advantage. Haman, full of hubris doesn't even see it coming.
