Here is the link to the article in wired about the blue dragon:
Absurd Creature of the Week: This Crazy-Looking Sea Slug Has an Ingenious Secret Weapon
The blue dragon incorporates the stinging cells of the man of war into its own body and gains the ability to sting others. This as we said in the message, is something like us. We are stung by others and we incorporate that sting into ourselves ready to sting the next unsuspecting person to come our way.
Peter in I Peter 3:9 tells us that Christians should not return evil for evil or insult for insult. When we are stung, we should not sting someone else. But how can we do that? Only by hope in Jesus who takes the stings and sin into himself and buries them in the grave. The sins committed against us and the sins we committed are removed. We are set free from the cycle and able now to respond to evil with blessing.
The sermon can be heard here. (in a few days when it is online)
