Colossians 1:16-17(KJV)

16  For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him And he is before all things, and by him all things consist.

These verses speak of ‘time’ before all things were created. By extension as God created all things God becomes outside of time and dimensionality at this stage. It is this author’s view  that these are unknowable and will remain so throughout eternity.

Also, it  seems reasonable to describe anyone created at this changeover as  ‘always’, ‘eternal’, and ‘everlasting’ and the Bible does indeed do this (Proverbs 8:23)
