2 Peter 2:20
For if, after they have escaped the defilements of the world by the knowledge of our Lord and Savior Jesus Christ, they are again entangled in them and overcome, the last state has become worse for them than the first — the knowledge (epignōsis) that offers escape is the same knowledge Peter elsewhere prescribes for spiritual growth. The return to defilement suggests apostasy more grave than initial ignorance. The last state (eschata) being worse than the first invokes a principle Jesus teaches in Matthew 12:45.
