• “in no way alarmed by your opponents – which is a sign of destruction [apoleia] for them, but of salvation for you, and that too, from God,” (Philippians 1:28).
• “whose end is destruction [apoleia], whose god is their appetite, and whose glory is in their shame, who set their minds on earthly things,” (Philippians 3:19).

Philippians 1:28 at 3:19 are sometimes used by annihilationists to support their idea that when a person is judged by God, he will stop existing. They presuppose that the word “destruction” means that they will not exist. In both of these two verses, the word “destruction” is apoleia. I have done an analysis of every single occurrence of the Greek word apoloeia, ἀπώλεια, in the entire New Testament. You can see it here:  Word study on apoleia, destroy.  I quote from that article.

“The Greek word apoleia is used in the New Testament to designate destruction of persons, objects, and institutions. When it comes to persons such as Judas Iscariot (John 17:12) and the Antichrist (2 Thess. 2:3), the meaning of destruction is open. In other words, the contexts do not necessitate nonexistence or continued existence. The word is used of spiritual death (Matt. 7:13; Rom. 9:22; Heb. 10:39; Rev. 17:8, 11) but again, exactly what the nature of this spiritual death is, whether it be existence or nonexistence, is not stated.”

Now, conditionalists will claim that the word destruction (apoleia, ἀπώλεια) in these two verses must mean nonexistence. But that is reading into the text what is not there. It is a common mistake for people to assume a word means something without really analyzing the context to see if such an interpretation is necessary.  In the case of Philippians 1:28 and 3:19, with the word apoleia is used for people, but the nature of the destruction is not specified.  So, the two verses cannot be used to prove annihilationism.
