So if we are to believe you then there was a an existence when "time" was not a part of any age.
Let us look at this verseagain:
"He has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. This grace was given us in Christ Jesus before the beginning of time (xρόνος)" (2 Tim.1:9).
Richard Trench writes,
"Χρόνος is time, contemplated simply as such; the succession of moments" (
Trench's New Testament Synonyms of the New Testament).
When the universe was created a succession of moments came into existence. Therefore, in the eternal state all things with God are simultaneous, meaning there was no succession of moments.
