As the apostle Peter puts it, they use “counterfeit words”​—words that resemble truth but that are actually as worthless as counterfeit money.​—2 Peter 2:3.

What is their aim? Peter adds: “They will exploit you.” Indeed, no matter what apostates may say to the contrary, the real aim of intruders is “to steal and slay and destroy.” (John 10:10) Beware of such strangers!
