Jesus said, “And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand” (John 10:28).
Notice the individual words of Jesus and the structure of the sentence. He uses the word neither, showing us that the statements before and after this word are stand-alone, independent truths. “They shall never perish” is a truth that stands by itself.
To know what Jesus meant by “never perish”, we must understand those two words.
The word never is defined as “at no time, on no occasion; not at all, in no way”; “not ever; not at any time; at no time; in no degree”. The word perish means “to suffer destruction; to incur spiritual death, be lost”; “to die; to lose life in any manner; to be destroyed; to be injured or tormented”.
Words have meaning, and what Jesus meant by “they shall never perish” can be understood quite clearly from the meanings of never and perish.
